# Calculate the molecular mass of the CuSO4 . 5H2O?

Molecular mass is considered the total sum of the masses of the atoms or elements included in the molecule. By interpreting the substance provided, we can calculate the molecular mass of the molecule:

1. Identify the molecule formula
2. The number of atoms presents in each element of the compound is calculated using the formula.
3. Multiply the atomic weight of each element with the number of atoms of that particular element
4. Likewise, do it for all the elements in the compound
5. Add all the values obtained in the step above
6. Then add the unit as grams/mole, and you can find the molecular mass of the compound

## Molecular mass of CuSO4. 5 H2O

The atomic mass of H is 1 g
The atomic mass of O is 16 g
The atomic mass of Cu is 63.5 g
The atomic mass of S is 32 g

Molar mass of CuSO4. 5 H2O = Atomic mass of Cu + Atom mass of S + (4 × Atomic mass of O) + [5 × {2 × Atomic mass of H + Atomic mass of O}]

Molar mass of CuSO4. 5 H2O = 63.5 + 32 + (4 × 16) + 5 (2 + 16) g

Molar mass of CuSO4. 5 H2O = 63.5 + 32 + 64 + 90 g

Molar mass of CuSO4. 5 H2O = 249.5 g
