What is the solubility of a salt if 0.4g of it is obtained on evaporating 200 $cm^{3}$ of its saturated solution to dryness?

A.

0.08 $gdm^{-3}$

B.

2.00 $gdm^{-3}$

C.

8.00 $gdm^{-3}$

D.

80.00 $gdm^{-3}$

View answer & explanation

Correct answer is B

1000 $cm^{3}$ = 1 $dm^{3}$

200 $cm^{3}$ = 0.2 $dm^{3}$

⇒ 0.2 $dm^{3}$ contains 0.4g

hence, solubility of the salt which is the amount of the salt dissolvable in 1 $dm^{3}$ is

$\frac{0.4g}{0.2dm^{3}} = 2.0gdm^{-3}$
