Molar and molecular weight of Pb(NO3)2

• Molecular formula: Pb(NO3)2 or N2O6Pb
• Relative molecular weight of Pb(NO3)2: 331.2098
• Molar mass of Pb(NO3)2: 331.2098 g/mol (0.33121 kg/mol)

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

• Mr[Pb(NO3)2] = Ar[N] * 2 + Ar[O] * 6 + Ar[Pb] = 14.0067 * 2 + 15.9994 * 6 + 207.2 = 331.2098
• Molar mass (kg/mol) = Mr[Pb(NO3)2] : 1000 = 331.2098 : 1000 = 0.33121 kg/mol

Pb(NO3)2: percent composition by element

• Nitrogen (N) = 28.0134 : 331.2098 * 100 = 8.458 %
• Oxygen (O) = 95.9964 : 331.2098 * 100 = 28.984 %
• Lead (Pb) = 207.2 : 331.2098 * 100 = 62.559 %
