Molar mass of butane Rating: 4,2/10 1315 reviews

The molar mass of a substance is the mass of one mole of that substance, and it is typically measured in grams per mole. Molar mass is an important concept in chemistry because it allows us to convert between the mass of a substance and the number of moles of that substance. In this essay, we will discuss the molar mass of butane, a hydrocarbon with the chemical formula C4H10.

Butane is a colorless, flammable gas that is commonly used as a fuel for lighters and portable stoves. It is also used as a feedstock in the petrochemical industry to produce a variety of chemicals, such as plastics and solvents. Butane is composed of four carbon atoms and ten hydrogen atoms, as indicated by its chemical formula.

To calculate the molar mass of butane, we need to add up the atomic weights of all of the atoms in its chemical formula. Carbon has an atomic weight of 12.0107 grams per mole, while hydrogen has an atomic weight of 1.00794 grams per mole. Using these values, we can calculate the molar mass of butane as follows:

Molar mass of butane = (4 x 12.0107 g/mol) + (10 x 1.00794 g/mol) = 48.0428 g/mol + 10.0794 g/mol = 58.1222 g/mol

Thus, the molar mass of butane is 58.1222 grams per mole. This value is important because it allows us to convert between the mass of butane and the number of moles of butane. For example, if we have 50 grams of butane, we can use the molar mass to calculate that we have 0.86 moles of butane, using the following formula:

Number of moles = mass / molar mass = 50 g / 58.1222 g/mol = 0.86 moles

In conclusion, the molar mass of butane is 58.1222 grams per mole, and it is a useful value for converting between the mass and the number of moles of this hydrocarbon. Understanding the molar mass of butane and other substances is an important part of chemistry, as it allows us to perform chemical calculations and understand the behavior of these substances at the molecular level.

This section needs expansion. Gas collection over water. An Alkane is when the compound is formed by single bonds connecting the carbons and hydrogens. Before collection, the gradu- ated cylinder is filled with water and inverted in a trough of water. Assume that butane is an ideal gas and that one mole has a volume of 22 L at STP.

If only part of the pipet was immersed in boiling water, so the temperature in part of the pipet was less than that of the water bath, then the temperature and part of the pipet would actually be less than what was originally recorded. Cyclobutane itself is of no commercial or biological significance, but more complex derivatives are important in biology and biotechnology. How many sigma and pi bonds are in butane? The composition of most present-day aerosol propellants is a mixture of butane isomers and propane. Watts' Dictionary of Chemistry. Assume that butane is an ideal gas and that one mole has a volume of 22 L at STP.

Water at 28°C has a higher vapor pressure than water at 20°C. It can vary between trials of an experiment, and it commonly defined as the deviation from the true accepted value. This ensures that the pressure of gas inside the graduated cylinder will be the same as the atmospheric pressure. R is the gas constant. Derivatives of cyclobutane are called cyclobutanes. Is 1-butene saturated or unsaturated? Snelling identified these gases as components in gasoline and found that if they were cooled, they could be stored in a volume-reduced liquified state in pressurized containers.

Although the most convenient gas for this is butane, other gases may be available in similar small cylinders. Line up the level of water in the flask with the water level in the beaker. How many grams of butane are in a lighter? The connection must be gas-tight and secure. Attach one end of the plastic tubing to the gas outlet on the lighter. Although this error is quite minor, it is most likely due to uncertainties of the materials used in the experiment. It has four gas variables: pressure P , volume V , number of mole of gas n and temperature T. Its insolubility in water enables the gas to be collected in water-filled graduated cylinder to get precise amount of gas.

Retrieved 5 December 2019. What percentage of the starting copper was consumed in this reaction? Which of the following is 1-butene? Record the volume of gas in the graduated cylinder in your lab notebook. Is 1-butene the same as 1 Ene? The mass of butane is the difference between the before and after mass of the butane lighter. Assume room temperature 22°C and atmospheric pressure 1 atm for your calculations. The experiment has established the mass of 1 dm 3, so the mass of 1 mole is simply 24 times that mass. Conclusion The purpose of this experiment was to determine the molar mas of butane gas. Table 1 lists the vapor pressure for water around room temperature.

It was discovered by the chemist Edward Frankland in 1849. For best results, immerse the lighter in water before measuring its mass. Why does Butyne have two isomers? Have a student helper hold the inverted graduated cylinder filled with water in the pneumatic trough. So for that, have a look at the periodic table given below.

The result is pressure of the collected gas, often referred to as the dry gas. Wet natural gas is further refined, yielding ethane, propane, and butane gases. Lighter refill cans should make a simple connection to tubing of appropriate diameter. Molar mass of Butane C4H10 is 58. The mean, or average, denoted x r, is the sum of all values in a set divided by the number of values, n. Remember to account for the partial pressure of water vapor. You can see that in Butane, there are 4 Carbon atoms and 10 Hydrogen atoms.

Subsequently, three trials will be performed where the precision and accuracy of your answer will dictate a portion of your grade. Chemicals Butane Equipment a water trough cigarette lighter 25 mL graduated cylinder barometer top-loading balance thermometer small plastic tubing Experiment 7 Experimental Procedure During this experiment, a total of four trials will be performed. Alkenes are hydrocarbons which contain carbon-carbon double bonds. Then we recorded the final volume of water, and repeated the experiment until we had three trials. Then we measured the mass of the cigarette lighter, and then slowly released butane gas bubbles into the beaker so that the bubbles collected at the top, where there was no air. Trail one is left out of the average due to it being a much lower value compared to trials two and three. Retrieved 20 September 2018.

In 1834, physicist Emil Clapeyron wrote an equation that assisted many chemists in understanding the behavior of everyday gases. Similarly, the retained names 'ethane', 'propane', and 'butane' were never replaced by systematic names 'dicarbane', 'tricarbane', and 'tetracarbane' as recommended for analogues of silane, 'disilane'; phosphane, 'triphosphane'; and sulfane, 'tetrasulfane'. The mass can be calculated using the following equation. This requires the records of room temperature and pressure at the time of the experiment. This is a percent error of 6.
