🤓 Based on our data, we think this question is relevant for Professor Joens' class at FIU.

Solution: At 25oC the vapor pressure of pure butane (C4H10, MW = 58.12 g/mol) is p°b = 380.0 torr and the vapor pressure of pure hexane (C6H14, MW = 86.17 g/mol) is p°H = 32.0 torr. What is the total pressure at 25oC when mixing equal grams of butane and hexane?
