Molar and molecular weight of CrO4

• Relative molecular weight of CrO4: 115.9937
• Molar mass of CrO4: 115.9937 g/mol (0.11599 kg/mol)

Calculation of the relative molecular and molar mass of CrO4

• Mr[CrO4] = Ar[Cr] + Ar[O] * 4 = 51.9961 + 15.9994 * 4 = 115.9937
• Molar mass (kg/mol) = Mr[CrO4] : 1000 = 115.9937 : 1000 = 0.11599 kg/mol

CrO4: percent composition by element

• Chromium (Cr) = 51.9961 : 115.9937 * 100 = 44.827 %
• Oxygen (O) = 63.9976 : 115.9937 * 100 = 55.173 %
