1-propanol (p*1 = 20.9 torr at 25 °C) and 2-propanol (p*2 = 45.2 torr at 25 °C) form ideal solutions in all proportions. Let x1 and x2 represent the mole fractions of 1-propanol and 2-propanol, respectively, in a liquid mixture and y1 and y2 represent the mole fractions of each in the vapor phase For a solution of these liquids with x1 = 0.510, calculate the composition of the vapor phase at 25 °C if the vapor above the liquid phase is composed only of 1-propanol and 2-propanol.

Plz mark brainliest 30 points 1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s. 2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
