Answer:

6 mol

Step-by-step explanation:

Discussion

The answer is very nearly six. I will use rounded whole numbers to get the molar mass. Every periodic table is different so you will have to redo my numbers using your periodic table.

The trick is to find 1 mole of CH4 and divide that into 96.

Givens

96.0 grams of CH4

Solution

Find 1 mol of CH4

1 * 1C = 1 * 12 = 12 grams of Carbon in 1 mol of CH4

4 * H = 4 * 1 = 4 grams of Hydrogen in 1 mol of CH4

Total = 16 grams of C and H in 1 mol of CH4

Find 96 grams in mols.

Formula

mol = given mass / molar mass

given mass = 96 grams

molar mass = 16 grams

Mol = 96 / 16

Answer: mol = 6
