Given,
Molality = .5M
We know, Kf = 1.86
Now,
Δ T = M x Kf
= 1.86 * 0.5
= 0.93 °C
Now,
Freezing point = Initial freezing point - Δ T
= 0°C - 0.93°C
= -0.93°C
So, the answer is A

A particular unknown solid depresses the freezing point of stearic acid (Kf =4.5 °C/molal) by 3.5 C. If you dissolve the same solid in H2O (Kf = 1.86 C/molal) to the same final molality as you had it in
