Question

A soil sample was taken from agricultural land and was weighed. The mass of the soil was found to be 50 g. 100 mL of water was taken in a measuring cylinder and added into the soil sample. The soil absorbed 80 mL of water and rest left in the measuring cylinder. Calculate the absorption rate of water by the soil.

Answer 1

Answer:

 The absorption rate of water can be calculated by the formula given below

Absorption rate=−(V1)initial volume of water���������� ����=−(�1)������� ������ �� �����

(V2)final=volume of watermassofsoil(w)×100(�2)�����=������ �� ���������������(�)×100

=V1−V2w×100=�1−�2�×100

Given, initial volume of water = 80 mL

Final volume of water = 60 mL

Mass of the soil = 40gm

Therefore, the percentage of water absorbed

=V1−V2w×100=�1−�2�×100

=80−6040×100%=80−6040×100%

=2040×100%=2040×100%

=50%=50%

Ans= 50% of the water has been absorbed by the soil.
