Reduction in volume R=42.5-26.8

=15.7cc

=15.7gm

% reduction in water content =51 to 1g=32% w=\frac{M_{w}}{M_{s}}=0.32

$M_{s}=\frac{M_{w}}{0.32}=\frac{15.7}{0.32}$ =49.06gm

Initial $M_{w}$ in soil sample=0.51 Ms= $0.51 \times 49.06$

=25.02gm Volume of water initially

$V_{s}$ =volume of solids=42.5-25.05

=17.478 cc

G $\frac{M_{s}}{V_{s}\times P_{w}} =\frac{49.06}{17.478 \times 1}$

=2.806
