Molar and molecular weight of Be(OH)2

• Molecular formula: Be(OH)2 or H2BeO2
• Relative molecular weight of Be(OH)2: 43.026862
• Molar mass of Be(OH)2: 43.026862 g/mol (0.04303 kg/mol)

Calculation of the relative molecular and molar mass of Be(OH)2

• Mr[Be(OH)2] = Ar[H] * 2 + Ar[Be] + Ar[O] * 2 = 1.00794 * 2 + 9.012182 + 15.9994 * 2 = 43.026862
• Molar mass (kg/mol) = Mr[Be(OH)2] : 1000 = 43.026862 : 1000 = 0.04303 kg/mol
