Correct Answer - Option 1 : 0.222
Concept:
Water content formula is given by:
w = Ww/Ws
where,
w = Water content
Ww = Weight of water
Ws = Weight of solids
Calculation:
Given data :
Weight of unsaturated sample = 220 g
Weight of dried sample = Weight of solids, Ws = 180 gm
Now, finding the weight of water, Ww
So, Ww = Weight of unsaturated sample - Weight of dried sample
= 220 - 180 = 40 g
So, Water content, w = \(40 \over 180\) = 0.222
Note: There is no use of sample volume in finding out water content
