Question

Find molar mass of K4[Fe(CN)6]

Answer 1

Molar mass= 4×39 + 56 + 12×6 + 14×6=368

Answer 2

Answer:

The molar mass of K4[Fe(CN)6] is 368 g/mol.

Explanation:

• In chemistry, the molar mass of a chemical compound is determined by dividing its mass by the molecular weight of the component that makes up the sample.
• The molar mass of a substance is a bulk attribute rather than a molecular one.
• The compound's molar mass is an average over numerous samples, which frequently have different masses because of isotopes.
• The molar mass of the given compound = sum of molar masses of 4 potassium atoms, 1 iron atom, 6 carbon atoms and 6 nitrogen atoms
• Molar mass = 4 (molar mass of K) + molar mass of Fe +  6 (molar mass of C) + 6 (molar mass of N)
• Molar mass = 4 (39) + 56 + 6 (12) + 6 (14) = 156 + 56 + 72 + 84 = 368 g/mol

The molar mass of K4[Fe(CN)6] is 368 g/mol.
