Introduction

Propane is a widely used hydrocarbon gas that serves as a fuel source in various applications, including cooking, heating, and as a fuel for vehicles. The chemical formula for propane is $CH_3 CH_2 CH_3$ . In this article, we will calculate the molar mass of propane and provide a detailed explanation of the process involved.

Understanding the Chemical Formula

The chemical formula for propane, $CH_3 CH_2 CH_3$ , indicates that it is a hydrocarbon composed of three carbon atoms and eight hydrogen atoms. The formula can be broken down into its constituent parts, with each carbon atom bonded to three hydrogen atoms and the remaining hydrogen atoms bonded to the adjacent carbon atoms.

Calculating the Molar Mass of Propane

To calculate the molar mass of propane, we need to determine the atomic masses of carbon and hydrogen. The atomic mass of carbon is 12.01 g/mol, and the atomic mass of hydrogen is 1.008 g/mol.

The molar mass of propane can be calculated using the following formula:

Molar mass of propane = (3 x atomic mass of carbon) + (8 x atomic mass of hydrogen)

Step-by-Step Calculation

Calculate the mass of carbon in propane: Multiply the atomic mass of carbon by the number of carbon atoms in propane.

Mass of carbon in propane = 3 x 12.01 g/mol = 36.03 g/mol

Calculate the mass of hydrogen in propane: Multiply the atomic mass of hydrogen by the number of hydrogen atoms in propane.

Mass of hydrogen in propane = 8 x 1.008 g/mol = 8.064 g/mol

Calculate the molar mass of propane: Add the mass of carbon and hydrogen in propane to obtain the molar mass.

Molar mass of propane = 36.03 g/mol + 8.064 g/mol = 44.094 g/mol

Rounding the Answer

The molar mass of propane is 44.094 g/mol. To round the answer to 2 decimal places, we get:

Molar mass of propane = 44.09 g/mol

Conclusion

In this article, we calculated the molar mass of propane using its chemical formula, $CH_3 CH_2 CH_3$ . We determined the atomic masses of carbon and hydrogen and used them to calculate the molar mass of propane. The result is 44.09 g/mol, which is the molar mass of propane rounded to 2 decimal places.
