The molecular formula of Mohr's salt is ...

The molecular formula of Mohr's salt is `(NH_(4))_(2)SO_(4)FeSO_(4).6H_(2)O`
Find the number of atoms of each element.

Text Solution

Verified by Experts

Molecular mass of Mohr.s salt = 2N + 20H + 25 + Fe + 14O
`=2xx14+20xx1+2xx32+56+14xx16=392`
Mass of percentage of N `=(2xx14)/(392)xx100=7.14`
Mass of percentage of H `=(20xx1)/(392)xx100=5.10`
Mass of percentage of S `=(2xx32)/(392)xx100=16.23`
Mass of percentage of Fe`=(1xx56)/(392)=100=14.28`
Mass of percentage of O `=(14xx16)/(392)=100=57.4`
