Answer: Molar mass of [tex]CuSO_4.5H_2O[/tex] is 249.68 g/mol.
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.
[tex]CuSO_4.5H_2O[/tex] 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 [tex]CuSO_4.5H_2O[/tex] = 63.5(1)+32.06(1)+16.00(9)+1.008(10)=249.68 g
Molar mass of [tex]CuSO_4.5H_2O[/tex] is 249.68 g/mol.
