Molar and molecular weight of Zn2SiO4

• Molecular formula: Zn2SiO4 or O4SiZn2
• Relative molecular weight of Zn2SiO4: 222.9011
• Molar mass of Zn2SiO4: 222.9011 g/mol (0.2229 kg/mol)

Calculation of the relative molecular and molar mass of Zn2SiO4

• Mr[Zn2SiO4] = Ar[O] * 4 + Ar[Si] + Ar[Zn] * 2 = 15.9994 * 4 + 28.0855 + 65.409 * 2 = 222.9011
• Molar mass (kg/mol) = Mr[Zn2SiO4] : 1000 = 222.9011 : 1000 = 0.2229 kg/mol

Zn2SiO4: percent composition by element

• Oxygen (O) = 63.9976 : 222.9011 * 100 = 28.711 %
• Silicon (Si) = 28.0855 : 222.9011 * 100 = 12.6 %
• Zinc (Zn) = 130.818 : 222.9011 * 100 = 58.689 %
