Answer:
The composition of benzene is 0.77 and the composition of toluene is 0.23
Explanation:
The Raoult´s law is:
Where
P = total pressure of solution benzene-toluene
PA⁰= vapor pressure of benzene = 95 torr
PB⁰ = vapor pressure of toluene = 28 torr
xA = mole fraction of benzene
xB = mole fraction of toluene
The total pressure of the solution is:
The composition of benzene and toluene:
There are 2 possible correct answers. Those answers are A and C because atoms "fuse together" by sharing electrons, and both compounds react to water, as they both dissolve in it. I would choose C as my answer, though.

<span>Molarity is expressed as the number of moles of solute per volume
of the solution while molality is expressed as the number of moles solute per
mass of solution. We calculate as follows:</span>
5.74 mol / kg (1.238 kg/L) = 7.10612 mol / L or 7.11 M
