Answer: c) 50%
W1= Empty weight of the container = 40gm
W2= Weight of (Empty container + Wet soil sample) =100gm
W3= Weight of (Empty container + Dry soil sample) =80gm
W= Water Content=?
The formula of water content by oven drying method,
W = (W2-W3)/(W3-W1) x 100
W = (100-80)/(80-40) x 100
W = 50 %
Hence, the moisture content in a given soil sample is 50 %.
