What is the percentage water content of soil sample which weighed 180g when fresh and 120g when oven-dried?
- 20.14%
- 25.00%
-
33.33%
- 60.00%
The correct answer is: C
Explanation
Mass of fresh soil = 180g
Mass of over dried soil = 120g
Mass of water = 180g - 120g = 60g
% of Water = \(\frac{60g}{18og}\) x 100
= \(\frac{1}{3}\) x 100 = 33.33%
