Question- Two liquids, A and B, have vapor pressures at a given temperature of 24 mmHg and 36 mmHg, respectively. We prepare solutions of A and B at a given temperature and measure the total pressures above the solutions. We obtain the following data:
Solution Amt A (mol) Amt B (mol) P (mmHg)
1 1 1 302 2 1 283 1 2 324 1 3 33
Forecast the total pressure above a solution of 5 mol A and 1 mol B. State your respond to two significant figures as well as include the appropriate units.
