Question

calculate th molar mass of CuSo4.5H2O in which (Cu-63.5u,S-32u,O-16u,H-1u)​

Answer 1

Answer:

atomic mass of H = 1 g

atomic mass of O = 16 g

atomic mass of Cu =63.5 g

atomic mass of S = 32 g

now ,

molar mass of CuSO4.5H2O = atomic mass of Cu + atom 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 + 90 g

= 249.5 g
