What is the molar mass of the compound K4[Fe(CN)6] ?

To calculate the molar mass of K4[Fe(CN)6], we need to find the molar masses of each element in the compound and then add them together.

Molar mass of K: 39.10 g/mol
Molar mass of Fe: 55.85 g/mol
Molar mass of C: 12.01 g/mol
Molar mass of N: 14.01 g/mol

Adding the molar masses of each element in the compound:
4(K) + 1(Fe) + 6(C) + 6(N) = 4(39.10) + 55.85 + 6(12.01) + 6(14.01) = 156.40 + 55.85 + 72.06 + 84.06 = 368.37 g/mol

Therefore, the molar mass of K4[Fe(CN)6] is 368.37 g/mol.
