Molar and molecular weight of NF3

• Molecular formula: NF3 or F3N
• Relative molecular weight of NF3: 71.0019096
• Molar mass of NF3: 71.0019096 g/mol (0.071 kg/mol)

Calculation of the relative molecular and molar mass of NF3

• Mr[NF3] = Ar[F] * 3 + Ar[N] = 18.9984032 * 3 + 14.0067 = 71.0019096
• Molar mass (kg/mol) = Mr[NF3] : 1000 = 71.0019096 : 1000 = 0.071 kg/mol

NF3: percent composition by element

• Fluorine (F) = 56.9952096 : 71.0019096 * 100 = 80.273 %
• Nitrogen (N) = 14.0067 : 71.0019096 * 100 = 19.727 %
