Question

calculate the relative molecular mass of CuSO4​

Answer 1

Answer:

Molecular mass of a compound is the sum of atomic masses of each element present in the molecule.

Molecular mass = atomic mass of Cu + atomic mass of S + (9 × atomic mass of O) + (10 × atomic mass of H) =63.5+32+9×16+10×1=249.5 gm/mole
