Expert Solution

Step 1

Mass of moist soil(M_moist)=721.2 Kg

The volume of sample(V)=0.450 m³

Mass of dry soil(M_dry)=721.2 Kg

Specific gravity(G)=2.68

a) water content(w)= $\frac{M_{m o i s t} - M_{d r y}}{M_{m o i s t}} \times 100$

$w = \frac{721.2 - 633.9}{721.2} \times 100 w = 12.1 % = 0.121$
