Answer:
Vapour pressure of benzene over the solution is 253 torr
Explanation:
According to Raoult's law for a mixture of two liquid component A and B-
vapour pressure of a component (A) in solution =
vapour pressure of a component (B) in solution =
Where are mole fraction of component A and B in solution respectively
are vapour pressure of pure A and pure B respectively
Here mole fraction of benzene in solution is 0.340 and vapour pressure of pure benzene is 745 torr
So, vapour pressure of benzene in solution =
= 253 torr
Given concentration of NaCl=15%
Means ,
In every 100g of Solution 15g of NaCl is present .
Now
- Given mass=250g
So ,
<u>37.5g of NaCl present in 250g of solution.</u>
