`15 g` of a solute in `100 g` of water makes a solution of freeze at `-1^(@)C.30g` of a solute in `100 g` of water will give a depression in `f.pt.` equal to:

A

(a) `-2^(@)C`

B

(b) `0.5^(@)C`

C

(c ) `2^(@)C`

D

(d) `1^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta T prop w` if other factors are constant,
Thus `(Delta T)/(1) = (30)/(15)`, `:. Delta T = 2`
