The ratio of number of water molecules in Mohr's salt and potash alum is $\times 10^{- 1} .$ (Integer answer)

Answer:

5.00

Solution:

Mohr's salt $= {FeSO}_{4} {({NH}_{4})}_{2} {SO}_{4} \cdot 6 H_{2} O$
Potash alum $= KAl {({SO}_{4})}_{2} \cdot 12 H_{2} O$
So water molecule ratio $= (\frac{6}{12}) = \frac{1}{2} = 0.5 = 5 \times 10^{- 1}$
