Question

I. An ideal solution of two homologous liquid alkane compounds have an
overall vapor pressure of 550 mmHg when alkane A is 75mol% and alkane B is
25mol% in liquid mixture. At the same temperature condition, the overall
vapor pressure emanating from the solution is increased by 10mmHg when
mol fraction of alkane A is 0.80 in a liquid mixture with alkane B alone.
a.) What are the corresponding vapor pressures of the pure alkane compound
compounds, separately?
b.) Calculate the vapor pressure of a resulting solution obtained by mixing 9.5
moles of alkane A with 0.5 mole of alkane B.
