Question

calculate the molecular mass of the CuSO4.5H2O(Cu-63.5,S-32,O-16,H-1)​

Answer 1

Explanation:

Cu - 63.5

S - 32

O - 16

H - 1

Now,

Molecular mass of CuSO4 , 5H2O = atomic mass of Cu + atomic mass of S + 4 × atomic mass of O + 5 × (2 × atomic mass of H +

atomic mass of O)

=63.5+32+4×16+5(2+16)g =63.5+32+64+90g

=249.5g

Therefore, the molecular mass of CuSO4.5H2O is249.5g.
