Answer 1

The ratio of number of water molecules in Mohr's salt and potash alum is 5 × 10^-1.

Explanation:

Formula of Mohr's salt = \[\ce{(NH4)_2 * Fe(SO4)2 * 6 H2O}\]

Formula of Potash alum = \[\ce{KAl (SO4)2 * 12H2O}\]

`"Number of water molecule in mohr's salt"/"Number of water molecule in potash alum" = 6/12`

= 0.5

= 5 × 10^-1
