A solution containing 0.4316 g of ethylene glycol (molar mass 
) in 40 mL of
shows boiling point deviation of 
. While a solution of 0.8216 g of an unknown solute in the same mass of solvent gave a boiling point elevation of 
. The molar mass of unknown solute is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
As we know,
Mass of the solute 
in first solution 
No. of moles of solute 
in first solution 
Suppose the mass of 40 mL of 
is 
.
For the first solution,
As, for second solution,
So, 
For the same solvent, 
Hence, 
So,
