Calculate the bulk density of a 100 cm3 soil sample that has a 15 percent gravimetric (or mass-based) water content and weighs 130 g.

Bulk density of the given soil sample = 1.3 g/cm³

Explanation:

The bulk density of a soil is equal to the dry weight of the soil divided by the total volume of the soil. It is also known as the dry bulk density.

The formula of dry bulk density is:

Bulk density = Dry weight of the soil (g) : volume of soil (cm³)

Given: dry weight of soil = 130 g, volume of soil = 100 cm³

Therefore,

Bulk density = Dry weight of the soil (g) : volume of soil (cm³) = 130 g : 100 cm³ = 1.3 g/cm³.

Therefore, Bulk density of the given soil sample = 1.3 g/cm³
