Answer:
The value of 
for xylene is 4.309°C/m.
The molar mass of pentane using this data is 73.82 g/mol.
Explanation:
where,
=depression in freezing point
= freezing point constant
we have :
1) freezing point constant for xylene = =?
Mass of toluene = 0.193 g
Mass of xylene = 2.532 kg = 0.002532 kg ( 1 g =0.001 kg)
The value of for xylene is 4.309°C/m.
2)
Mass of pentane = 0.123 g
molar mass of pentame= M
Mass of xylene = 2.493 g = 0.002493 kg
Freezing point Constant of xylene =
M = 73.82 g/mol
The molar mass of pentane using this data is 73.82 g/mol.
