Molar and molecular weight of MgSeO4

• Relative molecular weight of MgSeO4: 167.2626
• Molar mass of MgSeO4: 167.2626 g/mol (0.16726 kg/mol)

Calculation of the relative molecular and molar mass of MgSeO4

• Mr[MgSeO4] = Ar[Mg] + Ar[Se] + Ar[O] * 4 = 24.305 + 78.96 + 15.9994 * 4 = 167.2626
• Molar mass (kg/mol) = Mr[MgSeO4] : 1000 = 167.2626 : 1000 = 0.16726 kg/mol

MgSeO4: percent composition by element

• Magnesium (Mg) = 24.305 : 167.2626 * 100 = 14.531 %
• Selenium (Se) = 78.96 : 167.2626 * 100 = 47.207 %
• Oxygen (O) = 63.9976 : 167.2626 * 100 = 38.262 %
