Formula Used

The molar mass of a compound is calculated by summing the atomic masses of all atoms in its chemical formula. For CuSO4·5H2O:

Molar Mass = (Atomic Mass of Cu) + 4 × (Atomic Mass of S) + 4 × (Atomic Mass of O) + 5 × (2 × Atomic Mass of H + Atomic Mass of O)

Using standard atomic masses:

Copper (Cu): 63.55 g/mol
Sulfur (S): 32.07 g/mol
Oxygen (O): 16.00 g/mol
Hydrogen (H): 1.01 g/mol

The calculator uses these values to compute the total molar mass.

Worked Example

Let's calculate the molar mass of 1 mole of CuSO4·5H2O:

Copper: 63.55 g/mol × 1 = 63.55 g/mol
Sulfur: 32.07 g/mol × 1 = 32.07 g/mol
Oxygen in sulfate: 16.00 g/mol × 4 = 64.00 g/mol
Water molecules: (2 × 1.01 + 16.00) g/mol × 5 = 18.02 g/mol × 5 = 90.10 g/mol

Total molar mass = 63.55 + 32.07 + 64.00 + 90.10 = 249.72 g/mol

Note: The calculator uses precise atomic mass values from the latest IUPAC table.

Interpreting Results

The molar mass result represents the mass of one mole of CuSO4·5H2O. This value is crucial for:

Stoichiometric calculations in chemical reactions
Determining solution concentrations
Understanding the amount of substance in a given mass

For example, if you have 249.72 grams of CuSO4·5H2O, it contains 1 mole of the compound.
