Find out the percentage of hydrogen in the molar mass of methane.
Molar mass of CH4:
C = 1 * 12.01 g = 12.01 g
H = 4 * 1.01 g = 4.04 g
Total = 16.05 g
4.04 g/16.05 g * 100% = 25.171%
0.25171 * 20 g = 5.0342 g
There are about 5.03 grams of hydrogen in 20 grams of methane gas.

How many methane molecules of Ch4 have a mass equal to 3.20 grams?
One mole is equal to 6.022 x 1023 of anything. In this case, we are looking for molecules. So 1 mole=6.022 x 1023 molecules. We have 2.3 moles, so we want to know how many molecules are there. 2.3 mol CH4 x 6.022x1023 molecules CH4 / mol CH4 = 1.38x1024 molecules of CH4
How many grams in 5.0x1022 molecules of nitrogen monoxide?
5.0 X 10^22 molecules of NO (1 mole NO/6.022 X 10^23)(30.01 grams/1 mole NO) = 2.5 grams of nitrogen monoxide
