Question

1m aq. solution of a salt shows elevation in boiling point equal to 3 times of its k Determine
Freezing point of solution
Kwater) = 1.86 K kg mole1
(ii) Osmotic pressure at 27°C
Kf(water)=1.86K kg mole-1​

Answer 1

Answer:tb

Explanation:

First find i and then carryout the other using formula

Answer 2

Answer:

(i) Tf = – 5.58°C

(ii) π = 73.89 atm

Explanation:

ΔTb = i × Kb × m

—》3Kb = i × Kb × 1

—》 I = 3

(i) ΔTf = i × Kf × m

= 3 × 1.86 × 1

or ΔTf = –5.58°C

(ii) π = iCRT

= 3 × 1 × 0.0821 × 300

= 73.89 atm
