Question

the molecular massbof CuSo4.5H2O . At mass of Cu=63.5,S=32,O=16 and H=1​

Answer 1

CuSO4.5H20 ( Blue Vitrus ) :

Atomic weight of Cu = 63.5

Atomic weight of S = 32

Atomic weight of O = 16

Atomic weight of H = 1

Molecular weight of CuSO4.5H2O

= 63.5 + 32 + 4(16) + 10(1) + 5(16)

= 63.5 + 32 + 64 + 10 + 80

= 249.5 amu.
