You are given a new puppy as a birthday present and are eager to play with her. However, you soon come to realize that your new puppy has other plans. She decides to ransack your room and go after anything she can grasp in her mouth. One of the items is a rigid ball that has 5 grams of liquid ethanol in it from an experiment you did in class. The hot breath of the puppy vaporizes 50% of the ethanol to create an air-ethanol mixture at 50°C. After a few minutes, she releases the ball and the air-ethanol mixture comes to a new equilibrium state at 30°C. Taking the total pressure inside of the ball to be 1 atm, estimate the percent of ethanol that condenses at the final state. [HINT: Think carefully about how much ethanol is in the vapor state before the actual process starts. This is your starting amount.]
