Molar and molecular weight of Cs

• Relative molecular weight of Cs: 132.9054519
• Molar mass of Cs: 132.9054519 g/mol (0.13291 kg/mol)

Calculation of the relative molecular and molar mass of Cs

• Mr[Cs] = Ar[Cs] = 132.9054519 = 132.9054519
• Molar mass (kg/mol) = Mr[Cs] : 1000 = 132.9054519 : 1000 = 0.13291 kg/mol
