Molar and molecular weight of CHKO2

• Molecular formula: CHKO2 or KCHO2
• Relative molecular weight of CHKO2: 84.11574
• Molar mass of CHKO2: 84.11574 g/mol (0.08412 kg/mol)

Calculation of the relative molecular and molar mass of CHKO2

• Mr[CHKO2] = Ar[C] + Ar[H] + Ar[K] + Ar[O] * 2 = 12.0107 + 1.00794 + 39.0983 + 15.9994 * 2 = 84.11574
• Molar mass (kg/mol) = Mr[CHKO2] : 1000 = 84.11574 : 1000 = 0.08412 kg/mol

CHKO2: percent composition by element

• Carbon (C) = 12.0107 : 84.11574 * 100 = 14.279 %
• Hydrogen (H) = 1.00794 : 84.11574 * 100 = 1.198 %
• Potassium (K) = 39.0983 : 84.11574 * 100 = 46.482 %
• Oxygen (O) = 31.9988 : 84.11574 * 100 = 38.041 %
