Question

Mass of hydrated copper sulfate in CuSo4.5H2O​

Answer 1

Answer: Molar mass of
`CuSO_4.5H_2O` is 249.68 g/mol.

Step-by-step explanation:

Molar mass is the mass of 1 mole of the molecule. It is calculated by adding masses of all the atoms in the given molecule.

`CuSO_4.5H_2O` contains one atom of copper , 1 atom of sulphur, 9 atoms of oxygen and 10 atoms of hydrogen

Mass of copper = 63.5 g/mol

Mass of sulphur = 32.06 g/mol

mass of oxygen = 16.00 g/mol

Mass of hydrogen = 1.008 g/mol

Thus mass of
`CuSO_4.5H_2O` = 63.5(1)+32.06(1)+16.00(9)+1.008(10)=249.68 g

Molar mass of
`CuSO_4.5H_2O` is 249.68 g/mol.
