For this you need the atomic (molecular) mass of H2. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel.
3.00 moles H2 × 2.02 = 6.06 grams H2

How many atoms of hydrogens are in 3 moles of CH4?
There are 12 atoms of hydrogen in 3 moles of CH4. CH4 consists of one carbon atom and four hydrogen atoms. Since each mole of CH4 has 4 hydrogen atoms, 3 moles would have 3 * 4 = 12 hydrogen atoms in total.
How many atoms of sodium are present in 3 moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
How many moles of PCl3 contain 3.68 1025 chlorine atoms?
To find the number of moles of PCl3, you need to first calculate the number of moles of Cl atoms in 3.68 * 10^25 atoms. There are 3 Cl atoms in each molecule of PCl3, so you divide the number of Cl atoms by 3 to get the number of moles of PCl3.
How many atoms of Helium does it take to make Carbon?
