Molar and molecular weight of NO3

• Relative molecular weight of NO3: 62.0049
• Molar mass of NO3: 62.0049 g/mol (0.062 kg/mol)

Calculation of the relative molecular and molar mass of NO3

• Mr[NO3] = Ar[N] + Ar[O] * 3 = 14.0067 + 15.9994 * 3 = 62.0049
• Molar mass (kg/mol) = Mr[NO3] : 1000 = 62.0049 : 1000 = 0.062 kg/mol

NO3: percent composition by element

• Nitrogen (N) = 14.0067 : 62.0049 * 100 = 22.59 %
• Oxygen (O) = 47.9982 : 62.0049 * 100 = 77.41 %
