Question
what is The mass of the dry soil in a unit volume.
Solution
The mass of dry soil in a unit volume is referred to as the dry density of the soil. It is calculated by dividing the weight of the dry soil by its volume. This can be done using the following steps:
-
Collect a sample of the soil.
-
Measure the volume of the soil sample. This can be done by placing the soil in a container of known volume.
-
Dry the soil sample. This can be done by heating the soil in an oven at a temperature of 105 to 110 degrees Celsius until all the moisture has evaporated.
-
After the soil is completely dry, measure its weight using a balance.
-
Divide the weight of the dry soil by the volume of the soil sample. The result is the dry density of the soil, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
For example, if the weight of the dry soil is 1500 grams and the volume of the soil sample is 1000 cubic centimeters, the dry density of the soil would be 1.5 g/cm³.
