Molar and molecular weight of GaAsO4

• Relative molecular weight of GaAsO4: 208.6422
• Molar mass of GaAsO4: 208.6422 g/mol (0.20864 kg/mol)

Calculation of the relative molecular and molar mass of GaAsO4

• Mr[GaAsO4] = Ar[Ga] + Ar[As] + Ar[O] * 4 = 69.723 + 74.9216 + 15.9994 * 4 = 208.6422
• Molar mass (kg/mol) = Mr[GaAsO4] : 1000 = 208.6422 : 1000 = 0.20864 kg/mol
