Molar and molecular weight of FNa

• Molecular formula: FNa or NaF
• Relative molecular weight of FNa: 41.98817248
• Molar mass of FNa: 41.98817248 g/mol (0.04199 kg/mol)

Calculation of the relative molecular and molar mass of FNa

• Mr[FNa] = Ar[F] + Ar[Na] = 18.9984032 + 22.98976928 = 41.98817248
• Molar mass (kg/mol) = Mr[FNa] : 1000 = 41.98817248 : 1000 = 0.04199 kg/mol

FNa: percent composition by element

• Fluorine (F) = 18.9984032 : 41.98817248 * 100 = 45.247 %
• Sodium (Na) = 22.98976928 : 41.98817248 * 100 = 54.753 %
