A mixture of hexane (hex) and n-octane (oct) forming an ideal solution contains a mole fraction of hexane as 0.3. At 80°C, the vapor pressures of hexane and n-octane are 1062.7 and 175 mmHg, respectively. i. Calculate the partial pressures of hexane and n-octane above a 80°C solution. ii. Find the total vapor pressure of the solution at 80°C. iii. Calculate the mole fractions of hexane and n-octane in the vapor phase. iv. Draw a representative graph showing pressures (P, Phex, Poct, P hex, P"oct) versus xhex, liquid.
