Suppose water forms a regular solution with a solute, which we designate with a 2. suppose the mole fraction of water in this solution is χ1=0.75. suppose the vapor pressure of water above this solution is p1=2029 pa. assume t=293k and the vapor pressure of pure water at t=293 k p1*=2536pa.
a calculate the activity coefficient of water y1 in this solution
b determine the exchange parameter w for the regular solution described above.
c for the regular solution described in parts a and b, calculate the osmotic pressure that it generates at t=293k. assume for water v1 = 1.80 x 10^-5 m/mol
