Question

100 mL of water was added dropwise to 100 g of dry soil, kept on filter paper in a funnel. The amount of water collected in graduated cylinder was found to be 60 mL. Calculate the percentage of water absorbed by the soil.​

Answer 1

Answer:

multiply to 100 or 60 then answer will came

Answer 2

Weight of soil = 50g

Initial volume of water in the measuring cylinder in mL = U

Final volume of water in the measuring cylinder in mL = V

Therefore, the volume of water absorbed by the soil in mL = (U – V)

Weight of water absorbed by the soil in g = (U – V)

Note: (1 mL of water has a weight equal to 1 g)

Percentage of water absorbed = (U - V) / 50 × 100%

In general, we can write,

Percentage of water absorbed = (U−V)W×100%

where,

U - Mass of the initial volume of water in the measuring cylinder in g

V - Mass of final volume of water in the measuring cylinder in g

W- Mass of sand in g
