During the determination of the shrinkage limit of a sandy clay, the following laboratory data was obtained:

Wet wt. of soil + dish = 91.04 g

Dry wt. of soil + dish = 78.22 g

Wt. of dish = 51.55 g

Volumetric determination of soil pat:

Wt. of dish + mercury = 430.80 g

Wt. of dish = 244.62 g

Calculate the shrinkage limit of the soil, assuming ρs = 2.65 Mg/m3.?
