100 ml of water was taken in a measuring cylinder. this water was added dropwise to 50 gm of dry soil kept on filter paper in a funnel. when the water just started dripping from the soil in the funnel the amount of water left in the measuring cylinder was found to be 80 ml. calculate the percentage of water absorb
ed by this soil
Answers
40%
-80 ML =20 ML
20 ML /50 GM
% = 2/5*100
=40%
Given:
Amount of water in measuring cylinder=100ml
Weight of dry soil=50g
Water left after dripping=80ml
To find:
The percentage of water absorbed by this soil
Solution:
We can find the percentage by following the steps given below-
We know that the water absorbed in the soil will be used to calculate its percentage in the soil.
The total amount of water=100ml
The amount of water absorbed= Total amount of water- the amount left after dripping
=100-80
=20ml
The percentage of water absorbed will be calculated as a percent of the weight of the soil.
The percentage of water absorbed in soil= The amount of water absorbed×100/ Weight of soil
=20×100/50
=20×2
=40%
Therefore, the percentage of water absorbed by this soil is 40%.
