Molar and molecular weight of K3Bi

• Molecular formula: K3Bi or BiK3
• Relative molecular weight of K3Bi: 326.2753
• Molar mass of K3Bi: 326.2753 g/mol (0.32628 kg/mol)

Calculation of the relative molecular and molar mass of K3Bi

• Mr[K3Bi] = Ar[Bi] + Ar[K] * 3 = 208.9804 + 39.0983 * 3 = 326.2753
• Molar mass (kg/mol) = Mr[K3Bi] : 1000 = 326.2753 : 1000 = 0.32628 kg/mol

K3Bi: percent composition by element

• Bismuth (Bi) = 208.9804 : 326.2753 * 100 = 64.05 %
• Potassium (K) = 117.2949 : 326.2753 * 100 = 35.95 %
