The solubility curve of KNO(3) in water...

The solubility curve of `KNO_(3) ` in water is shown below.

The amount of `KNO_(3)` that dissolves in 50 g of water at ` 40^(@)C` is closest to

A

100 g

B

150 g

C

200 g

D

50 g

Text Solution

Verified by Experts

The correct Answer is:
A
At ` 40^(@)C` solubility is 200 gm per 100 ml (approx)
i.e., 100 ml of water contains = 200 gm of `KNO_(3)` (approx)
50 ml of water contains = 100 gm (approx)
