Molar and molecular weight of NaBH4

• Molecular formula: NaBH4 or H4BNa
• Relative molecular weight of NaBH4: 37.83252928
• Molar mass of NaBH4: 37.83252928 g/mol (0.03783 kg/mol)

Calculation of the relative molecular and molar mass of NaBH4

• Mr[NaBH4] = Ar[H] * 4 + Ar[B] + Ar[Na] = 1.00794 * 4 + 10.811 + 22.98976928 = 37.83252928
• Molar mass (kg/mol) = Mr[NaBH4] : 1000 = 37.83252928 : 1000 = 0.03783 kg/mol

NaBH4: percent composition by element

• Hydrogen (H) = 4.03176 : 37.83252928 * 100 = 10.657 %
• Boron (B) = 10.811 : 37.83252928 * 100 = 28.576 %
• Sodium (Na) = 22.98976928 : 37.83252928 * 100 = 60.767 %
