Molar and molecular weight of RbOH

• Molecular formula: RbOH or HORb
• Relative molecular weight of RbOH: 102.47514
• Molar mass of RbOH: 102.47514 g/mol (0.10248 kg/mol)

Calculation of the relative molecular and molar mass of RbOH

• Mr[RbOH] = Ar[H] + Ar[O] + Ar[Rb] = 1.00794 + 15.9994 + 85.4678 = 102.47514
• Molar mass (kg/mol) = Mr[RbOH] : 1000 = 102.47514 : 1000 = 0.10248 kg/mol

RbOH: percent composition by element

• Hydrogen (H) = 1.00794 : 102.47514 * 100 = 0.984 %
• Oxygen (O) = 15.9994 : 102.47514 * 100 = 15.613 %
• Rubidium (Rb) = 85.4678 : 102.47514 * 100 = 83.403 %
