Molar and molecular weight of CrSO4

• Molecular formula: CrSO4 or CrO4S
• Relative molecular weight of CrSO4: 148.0587
• Molar mass of CrSO4: 148.0587 g/mol (0.14806 kg/mol)

Calculation of the relative molecular and molar mass of CrSO4

• Mr[CrSO4] = Ar[Cr] + Ar[O] * 4 + Ar[S] = 51.9961 + 15.9994 * 4 + 32.065 = 148.0587
• Molar mass (kg/mol) = Mr[CrSO4] : 1000 = 148.0587 : 1000 = 0.14806 kg/mol

CrSO4: percent composition by element

• Chromium (Cr) = 51.9961 : 148.0587 * 100 = 35.119 %
• Oxygen (O) = 63.9976 : 148.0587 * 100 = 43.224 %
• Sulfur (S) = 32.065 : 148.0587 * 100 = 21.657 %
