Hello there!
In this case, according to the given information, it turns out possible for us to infer this problem is about the application of the Gay-Lussac's gas law to relate the initial and final pressure and temperature as shown below:
Thus, solving for the final pressure, P2, and using the temperatures in Kelvins, we obtain:

Complete Question
You are given a solution containing a pair of enantiomers (A and B). Careful measurements show that the solution contains 98% A and 2% B. What is the enantiomeric excess?
Answer:
The value is
Explanation:
From the question we are told that
The percentage of enantiomer A is A = 98%
The percentage of enantiomer B is B = 2%
Generally the enantiomeric excess is mathematically represented as
=>
=>
Answer:
i=1.62 .
Explanation:
Let, i be the Van't Hoff Factor.
Moles of benzamide,=
Molality of solution, m=
Now, we know
Depression in freezing point, .....1
It is given that,
Putting all these values we get,
Now, moles of ammonium chloride=
molality =
Putting all these values in eqn 1.
We get,
i=1.62 .
Hence, this is the required solution.
