In part B, PLEASE solve for both nitrogen AND mek not just mek. Thank you.

2. Liquid methyl ethyl ketone (MEK) is introduced into a chamber containing nitrogen at 45C. The pressure rises and then levels off at 1060mmHg with liquid still present. For the system at equilibrium, calculate: (a) the number of degrees of freedom according to the Gibbs phase rule. Answer: Not given (b) the partial pressures and mole fractions of each component in the gas phase. Partial Answer: 218.2mmHg partial pressure and 0.206 mole fraction for MEK (c) the ratio of mass ( g ) of MEK vapour to volume (L) of gas. Answer: 0.793g MEK/L gas
