Level 1 – Vapor Pressure and Composition Calculation A student is investigating the effects of Raoult’s Law by preparing a liquid solution of compounds A and B. At 60 °C, the total solution boils. At this temperature, the student measures the following partial vapor pressures: Partial pressure of compound A: 400 torr Partial pressure of compound B: 360 torr Determine the percent composition (by mole fraction) of compounds A and B in the liquid solution. (Enter the relative percentages of A and B. Answer choice order may not match compound order above.)
