Molar and molecular weight of Zn(NO2)2

• Relative molecular weight of Zn(NO2)2: 157.42
• Molar mass of Zn(NO2)2: 157.42 g/mol (0.15742 kg/mol)

Calculation of the relative molecular and molar mass of Zn(NO2)2

• Mr[Zn(NO2)2] = Ar[Zn] + Ar[N] * 2 + Ar[O] * 4 = 65.409 + 14.0067 * 2 + 15.9994 * 4 = 157.42
• Molar mass (kg/mol) = Mr[Zn(NO2)2] : 1000 = 157.42 : 1000 = 0.15742 kg/mol

Zn(NO2)2: percent composition by element

• Zinc (Zn) = 65.409 : 157.42 * 100 = 41.551 %
• Nitrogen (N) = 28.0134 : 157.42 * 100 = 17.795 %
• Oxygen (O) = 63.9976 : 157.42 * 100 = 40.654 %
