What is the percentage water content of soil sample which weighed 180g when fres...

Question

What is the percentage water content of soil sample which weighed 180g when fresh and 120g when oven-dried?

A)
20.14%
B)
25.00%
C)
33.33%
D)
60.00%

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%
