Molar and molecular weight of CrO4Zn

• Molecular formula: CrO4Zn or ZnCrO4
• Relative molecular weight of CrO4Zn: 181.4027
• Molar mass of CrO4Zn: 181.4027 g/mol (0.1814 kg/mol)

Calculation of the relative molecular and molar mass of CrO4Zn

• Mr[CrO4Zn] = Ar[Cr] + Ar[O] * 4 + Ar[Zn] = 51.9961 + 15.9994 * 4 + 65.409 = 181.4027
• Molar mass (kg/mol) = Mr[CrO4Zn] : 1000 = 181.4027 : 1000 = 0.1814 kg/mol

CrO4Zn: percent composition by element

• Chromium (Cr) = 51.9961 : 181.4027 * 100 = 28.663 %
• Oxygen (O) = 63.9976 : 181.4027 * 100 = 35.279 %
• Zinc (Zn) = 65.409 : 181.4027 * 100 = 36.057 %
