Molar and molecular weight of H2CrO4

• Relative molecular weight of H2CrO4: 118.00958
• Molar mass of H2CrO4: 118.00958 g/mol (0.11801 kg/mol)

Calculation of the relative molecular and molar mass of H2CrO4

• Mr[H2CrO4] = Ar[H] * 2 + Ar[Cr] + Ar[O] * 4 = 1.00794 * 2 + 51.9961 + 15.9994 * 4 = 118.00958
• Molar mass (kg/mol) = Mr[H2CrO4] : 1000 = 118.00958 : 1000 = 0.11801 kg/mol

H2CrO4: percent composition by element

• Hydrogen (H) = 2.01588 : 118.00958 * 100 = 1.708 %
