Molar and molecular weight of HOOOOH

• Molecular formula: HOOOOH or H2O4
• Relative molecular weight of HOOOOH: 66.01348
• Molar mass of HOOOOH: 66.01348 g/mol (0.06601 kg/mol)

Calculation of the relative molecular and molar mass of HOOOOH

• Mr[HOOOOH] = Ar[H] * 2 + Ar[O] * 4 = 1.00794 * 2 + 15.9994 * 4 = 66.01348
• Molar mass (kg/mol) = Mr[HOOOOH] : 1000 = 66.01348 : 1000 = 0.06601 kg/mol

HOOOOH: percent composition by element

• Hydrogen (H) = 2.01588 : 66.01348 * 100 = 3.054 %
• Oxygen (O) = 63.9976 : 66.01348 * 100 = 96.946 %
