Question

calculate the molecular mass of the CU s o 4.5 H2O

Answer 1

Molecular mass of CuSO4
Atomic Mass of Cu= 64u
Atomic Mass of S= 32u
Atomic Mass of O= 16u
So, molecular mass of CuSO4=
=64u+32u+16u*4
=96u+64u
=160u



Molecular mass of H2O
Atomic Mass of H = 1u
Atomic Mass of O = 16u
Molecular mass of H2O =
= 1u*2+16u
= 2u+16u
= 18u
