help please idk if my answers are correct
step by step solving please

1. At a temperature of 298 K, two organic liquids are found to have equilibriurm vapor pressures that are in the ratio of 3 to 2. Find the mole fractions of the two in the vapor over a solution of the two with the mole fraction of the first component being 0.40 Find the fugacity of a sample of 1 mol of neon at T = 300 K and P = 10.0 bar if the equation of state V = RT/P + b holds and b = 0.075 L/mol. (V-molar volume) 2. How many grams of toluene must be dissolved in 500.0 g of benzene to lower the freezing point of benzene by 3.5 K? 3.

Explanation / Answer

given that

Pa/Pb=3/2

Xa=0.4

PaXa+PbXb=P

3k*0.4+2k*0.6=P

2.4k=P

Yb*P=Pb

Yb=2/2.4

Yb=1/1.2

2)

intergral (z-b)dp/p=fugacity coefficient by solving this we get answer.
