Answer 2

Answer:

$\bold{In \: this \: case :} \\ </p><p></p><p> \bold{Original \: mass \: of \: soil=170g} \\ \bold{Mass \: of \: dried \: soil=170g} \\ \bold{So, \: \: \: \: \: Mass \: of \: water \: in \: soil \: =200-170} \\ \bold{ \: \: \: \: \: \: \: \: \: \: =30g}$

$\bold{We \: know \: that:} \\ \bold{Percentage \: of \:water \: in \: soil \: = \: \frac{Mass \:of \: water \: in \: soil \: }{Original \: massof \: soil \: } \times 100}$

$\: \: \: \: \: \: \: \: \bold{ = \frac{30g}{200g} \times 100} \\ \: \: \: \: \bold{ = \frac{30}{2} } \\ \: \: \: \: \: \: 15 \: per \: cent$

Thus, the given sample of soil contains 15 per cent water in it. We can also say that the given sample of soil contains 15 per cent moisture in it. By saying that a soil contains 15 per cent water, we mean that 100 grams of this soil contains 15 grams of water.
