Molar and molecular weight of AsCl5

• Relative molecular weight of AsCl5: 252.1866
• Molar mass of AsCl5: 252.1866 g/mol (0.25219 kg/mol)

Calculation of the relative molecular and molar mass of AsCl5

• Mr[AsCl5] = Ar[As] + Ar[Cl] * 5 = 74.9216 + 35.453 * 5 = 252.1866
• Molar mass (kg/mol) = Mr[AsCl5] : 1000 = 252.1866 : 1000 = 0.25219 kg/mol
