For this problem, the Atomic Mass is not required. Take the mass in moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for the units to cancel.
2.5 moles H2 × (6.02 × 1023 atoms) = 1.51 × 1024 atoms

How many atoms of hydrogen are present in 1.5 lb of hydrogen peroxide which is 5.93 percent hydrogen. 1 lb equals 454 grams.?
First, calculate the total weight of hydrogen in 1.5 lb of hydrogen peroxide: 1.5 lb * 454 g/lb * 0.0593 = 128.97 g of H2O2 Then, convert this weight to the number of moles of hydrogen: 128.97 g / 34.0147 g/mol = 3.79 moles of H2O2 Since each mole of H2O2 has 2 moles of hydrogen atoms, there are 3.79 * 2 = 7.58 moles of hydrogen atoms. Finally, calculate the number of atoms: 7.58 moles * 6.022 x 10^23 atoms/mol = 4.56 x 10^24 atoms of hydrogen.
How many hydrogen atoms are in 738 grams of water?
To find the number of hydrogen atoms, we need to first determine the number of water molecules in 738 grams of water. Then, using the molecular formula of water (H2O), we know that each water molecule contains 2 hydrogen atoms. Finally, we can calculate the total number of hydrogen atoms by multiplying the number of water molecules by 2.
