What is the mass of 5 moles of hydrogen gas?
Answer: Hydrogen’s molar mass is 1.008 g/mol. Hydrogen gas’s formula is H2 meaning its composed of two hydrogens therefore its molar mass is 2.016 g/mol. 5 mol H2 x 2.016g/mol = 10.08 g.

1 mole of any molecule has 6.022 x 1022 molecules, 0.05 moles of N2 = 0.05 x 6.022 x 1022 molecules. 1 molecule of nitrogen has 14 electrons in it.
What is the formula for moles to grams?
Moles to grams example problem
Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.
