Question

The lab technician you recently hired tells you the following: Boss, an undisturbed sample of saturated clayey soil was brought to me from the Mission Valley site. I measured the mass of the sample to be 600 grams. I then measured the mass of the sample after placing it in the oven for 24 hrs. I found this mass to be 200 grams. Can you help me determine the water content?" Determine the water content.

Answer 1

Answer:

The water of the saturated clayed soil is 66.67 %.

Explanation:

Given;

mass of saturated clayed soil, $M_s$ = 600 g

mass of dry soil sample, $M_d$ = 200 g

mass of water content, $M_w$ = $M_s$ - $M_d$ = 600 g - 200 g = 400 g

The water content is determined as;

$M_w(\%) = \frac{M_s - M_d}{M_s} *100\%\\\\M_w(\%) = \frac{600-200}{600} *100 \% \\\\M_w(\%) = 66.67 \%$

Therefore, the water of the saturated clayed soil is 66.67 %.
