Molar and molecular weight of KHCO3

• Molecular formula: KHCO3 or CHKO3
• Relative molecular weight of KHCO3: 100.11514
• Molar mass of KHCO3: 100.11514 g/mol (0.10012 kg/mol)

Calculation of the relative molecular and molar mass of KHCO3

• Mr[KHCO3] = Ar[C] + Ar[H] + Ar[K] + Ar[O] * 3 = 12.0107 + 1.00794 + 39.0983 + 15.9994 * 3 = 100.11514
• Molar mass (kg/mol) = Mr[KHCO3] : 1000 = 100.11514 : 1000 = 0.10012 kg/mol

KHCO3: percent composition by element

• Carbon (C) = 12.0107 : 100.11514 * 100 = 11.997 %
• Hydrogen (H) = 1.00794 : 100.11514 * 100 = 1.007 %
• Potassium (K) = 39.0983 : 100.11514 * 100 = 39.053 %
• Oxygen (O) = 47.9982 : 100.11514 * 100 = 47.943 %
