What Is The Molar Mass Of CrSO4.3H2O?

The molar mass of CrSO4.3H2O can be calculated by adding the atomic masses of all the atoms in one formula unit.

The atomic masses of chromium (Cr), sulfur (S), oxygen (O), and hydrogen (H) are 52.00 u, 32.06 u, 16.00 u, and 1.01 u, respectively. The molar mass of water is 18.02 g/mol.

To calculate the molar mass of CrSO4.3H2O, we need to add up the atomic masses of one chromium atom, one sulfur atom, four oxygen atoms, six hydrogen atoms, and three water molecules:

Molar mass of CrSO4.3H2O = (1 x 52.00) + (1 x 32.06) + (4 x 16.00) + (6 x 1.01) + (3 x 18.02)

= 267.99 g/mol

Therefore, the molar mass of CrSO4.3H2O is 267.99 g/mol.
