The number of moles that are contained in the given mass of propane ( $C_3H_8$ is 1.7143 moles.

<u>Given the following data:</u>

Mass of propane = 75.6 grams.

<u>Scientific data:</u>

The molar mass of propane = 44.1 g/mol.

To calculate the number of moles that are contained in the given mass of propane ( $C_3H_8$ ):

<h3>How to calculate the moles of a compound.</h3>

In this exercise, you're required to determine the number of moles of propane that are contained in the given sample:

Mathematically, the number of moles contained in a chemical compound is given by this formula:

$Number\;of\;moles = \frac{mass}{molar\;mass}$

Substituting the given parameters into the formula, we have;

$Number\;of\;moles = \frac{75.6}{44.1}$

Number of moles = 1.7143 moles.
