Answer: 3.4008
Step-by-step explanation:
Answer: 3.4008
To determine the freezing point of the solution, we need to use the freezing point depression equation:
ΔT = Kf * m
Given:
Kf (benzene) = 5.12 °C/m
m = 0.41 m
Substituting the values into the equation:
ΔT = 5.12 °C/m * 0.41 m
ΔT = 2.0992 °C
To find the freezing point, we subtract the freezing point depression from the freezing point of the pure solvent (benzene). The freezing point of benzene is 5.5 °C.
Freezing point = FP (benzene) - ΔT
Freezing point = 5.5 °C - 2.0992 °C
Freezing point = 3.4008 °C
Therefore, the freezing point of the 0.41 m solution of C5H4 in benzene is approximately 3.4008 °C.
