There are

#### Explanation:

To answer this question, you must understand how to convert grams of a molecule into the number of molecules. To do this, you have to utilize the concepts of moles and molar mass.

A mole is just a unit of measurement. Avogadro's number is equal to

For example, one mole of hydrogen gas (

So the overall solution for this problem is to use molar mass of

One mole of methane equals 16.04 grams because a molecule of methane has an atomic weight of 16.04. The conversion factor will be 16.04 grams/mole.

When you multiple and divide everything out, you get
