Problem: (Hint: If you dont know where to start, try assuming you have 100g total of solution.) Consider two liquids A and B. The vapor pressure of pure A (molecular weight = 50 g/mol) is 225 torr at 25°C and the vapor pressure of pure B (molecular weight = 75 g/mol) is 90 torr at the same temperature. What is the total vapor pressure at 25°C of a solution that is 25% A amd 75% B by weight? 1. 76 torr 2. 225 torr 3. 335 torr 4. 203 torr 5. 135 torr 6. 191 torr 7. 108 torr 8. 115 torr 9. 124 torr
