Answer:
Gamma Radiation i hope this help u
Explanation:
Answer:
KI 1.0 M
Explanation:
Freezing point of a substance is a colligative property. This means that it depends on the amount of substance present is the system.
The freezing point is given by; T - Ta = K * m * i
Where;
T = freezing point of the pure solution
Ta = freezing point of the solution containing the solute
K = freezing point constant
m = molality of the solution
i= Van't Hoff factor
If we look at all the options provided, KI has only two particles in solution and a molality of 1.0 m hence it should exhibit the lowest freezing point of solution.
For the answer to the question above,
in this problem we can use the concept of freezing point depression since we are given the freezing point of the solution.
ΔT = -k(f) x m x i
-2.24 - 0 = -1.86 x m x 3
<span>m = 0.4014
</span>So the answer to your question is m = 0.4014
