2 An undisturbed soil sample has a wet density of 2.22 Mg/m³ when the water content is 10 percent. The specific gravity of the soil particles is 2.69.

(a) Approximate the submerged effective density for this soil.

(b) Determine the submerged effective density using the formula for an exact value.
