Question

D. Find out the molar masses of the
following compounds :
c. mohr's salt ​

Answer 1

Answer:

common name of copper sulphate crystal is blue vitroil.

chemical formula of copper sulphate crystal is  (copper sulphate pentahydrate).

we know,

atomic mass of Cu = 63.5 g/mol

atomic mass of S = 32g/mol

atomic mass of O = 16 g/mol

atomic mass of H = 1g/mol

now, molecular mass of  = 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 × 1 + 16)

= 63.5 + 32 + 64 + 90

= 249.5g/mol
