Question

Raman wanted to measure the percentage of water absorbed by a given soil sample. For this Raman took a plastic funnel, a filter paper (or a piece of newspaper sheet). He then took X g of dry, powdered soil and pour it into the funnel. He measured a certain amount of water in a measuring cylinder and pour it drop by drop on the soil. He did not let all the water fall in one spot and poured water all over the soil. He kept pouring water till it starts dripping. Which of the given formulas would be used by him to do so?

Given; ( X= Weight of soil taken); (U= Initial volume of water); (V= Final volume of water)

Solution

The correct option is **C** U−VX×100

The prcentage of water absorbed by a soil sample is given by :

U−VX×100

Where,

X= Weight of soil taken

U= Initial volume of water

V= Final volume of water

The prcentage of water absorbed by a soil sample is given by :

U−VX×100

Where,

X= Weight of soil taken

U= Initial volume of water

V= Final volume of water
