What Is The Molecular Weight Of Sodium Ferrocyanide Decahydrate?

The molecular weight of sodium ferrocyanide decahydrate can be calculated by adding the atomic weights of all the atoms in its chemical formula, which is Na4Fe(CN)6·10H2O.

The atomic weight of sodium (Na) is 22.99 g/mol, iron (Fe) is 55.85 g/mol, carbon (C) is 12.01 g/mol, nitrogen (N) is 14.01 g/mol, and oxygen (O) is 16.00 g/mol. The molecular weight of water (H2O) is 18.02 g/mol.

Therefore, the molecular weight of sodium ferrocyanide decahydrate can be calculated as follows:

[(4 x 22.99) + 55.85 + (6 x 12.01) + (6 x 14.01) + (10 x (2 x 1.01 + 16.00))] + (10 x 18.02)

= 839.96 g/mol

Thus, the molecular weight of sodium ferrocyanide decahydrate is 839.96 g/mol.
