Answer:
0.74°C
Explanation:
The freezing point depression is a colligative property that can be calculated using the following expression.
ΔTf = Kf . b
where,
ΔTf: depression in the melting point
Kf: freezing point depression constant
b: molality
The mass of the solvent (benzene) is:
The moles of solute (naphtalene) are:
The molality of naphtalene is:
ΔTf = Kf . b
ΔTf = (4.90°C/m) . 0.972m = 4.76°C
The melting point of the solution is:
5.50°C - 4.76°C = 0.74°C
