Question

A sample of moist soil with a wet mass of 1.0 kg and a volume of 0.64 liters (6.4 $\times$ 10$^{-4}$ m$^3$) was dried in the oven and found to have a dry mass of 0.8 kg. Assuming the typical value of particle density (2650 kg/m$^3$) for a mineral soil, what will be the volumetric moisture content?

• A. 37.5 %
• B. 22.5 %
• C. 31.25 %
• D. 25 %

Hint:

Using liters for both water volume and total soil volume simplifies the calculation.
Keep in mind: \( 1 \text{ kg} \) of water has a volume of exactly \( 1 \text{ liter} \).

Answer 1

The Correct Option is C
