Molar and molecular weight of Mg(NO3)2

• Molecular formula: Mg(NO3)2 or MgN2O6
• Relative molecular weight of Mg(NO3)2: 148.3148
• Molar mass of Mg(NO3)2: 148.3148 g/mol (0.14831 kg/mol)

Calculation of the relative molecular and molar mass of Mg(NO3)2

• Mr[Mg(NO3)2] = Ar[Mg] + Ar[N] * 2 + Ar[O] * 6 = 24.305 + 14.0067 * 2 + 15.9994 * 6 = 148.3148
• Molar mass (kg/mol) = Mr[Mg(NO3)2] : 1000 = 148.3148 : 1000 = 0.14831 kg/mol

Mg(NO3)2: percent composition by element

• Magnesium (Mg) = 24.305 : 148.3148 * 100 = 16.387 %
• Nitrogen (N) = 28.0134 : 148.3148 * 100 = 18.888 %
• Oxygen (O) = 95.9964 : 148.3148 * 100 = 64.725 %
