Question

If a 50 g sample of soil absorbs 15 ml of water, the moisture absorption is ______ %.
[1 ml of water weighs 1 g]

• A. 3
• B. 10
• C. 100
• D. 30

Answer 1

The correct option is D 30

Given:

• The weight of soil sample taken =50 g
• Volume of water absorbed by the soil sample =15 ml
• Weight of 1 ml of water = 1 g
• Therefore, weight of 15 ml of water = 15 g

Moisture absorbtion (%) = $\frac{\text{Weight of water absorbed by soil sample (g)}}{\text{Weight of soil sample}}\times 100$
= $\frac{15}{50}\times 100$ = 30%
