Question

What is the freezing point in °C) of a 0.743 m

aqueous solution of KCI?
Enter your rounded answer with
3 decimal places.

Answer 1

-0.276 Degrees C

Step-by-step explanation:

kf of water is 1.86

Freezing point depression= m x kf x i

i= ions present ( K+ Cl-) 1=2

1.86x2X.743= .276

Since its freezinf point depression the freezing point will lower

so

0-.276= -.276

Answer 2

Answer: -2.764
