Molar and molecular weight of CaO4Se

• Molecular formula: CaO4Se or CaSeO4
• Relative molecular weight of CaO4Se: 183.0356
• Molar mass of CaO4Se: 183.0356 g/mol (0.18304 kg/mol)

Calculation of the relative molecular and molar mass of CaO4Se

• Mr[CaO4Se] = Ar[Ca] + Ar[O] * 4 + Ar[Se] = 40.078 + 15.9994 * 4 + 78.96 = 183.0356
• Molar mass (kg/mol) = Mr[CaO4Se] : 1000 = 183.0356 : 1000 = 0.18304 kg/mol

CaO4Se: percent composition by element

• Calcium (Ca) = 40.078 : 183.0356 * 100 = 21.896 %
• Oxygen (O) = 63.9976 : 183.0356 * 100 = 34.965 %
• Selenium (Se) = 78.96 : 183.0356 * 100 = 43.139 %
