You want to convert grams of H 2 gas to moles. What conversion factor would you use?
A) 1.0/1 mol g B) 2.0g/1 mol C) 1 mol/1g D) 1 mol/2.0g

B?

Explanation:

In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles. Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
