Question

100 gm of a soil is taken and dried completely in sunshine. The mass of dried soil is found to be 70 gm. Calculate the percentage of water (or moisture) present in the given sample of the soil.

Answer 1

Answer:

So, here it is given that when 100 g of soil is dried completely then the mass of dried soil that is obtained is 70 g

We have to find the percentage of water that is present in the soil

Mass of water present in the soil = 100 - 70

                                                    = 30 g

Let x % be the percentage of water

Then, the mass of water = x % of 100

                          30 = (x/100) × 100

                            x = 30%

Explanation:

Hence, the percentage of water present in the given sample of the soil was 30 %
