A solution of pentane and ethanol (CH3CH2OH) that is 75% pentane by mass is boiling at 46.5 °C. The vapor is collected and cooled until it condenses to form a new solution. Calculate the percent by mass of pentane in the new solution. Here's some data you may need: normal boiling point vapor pressure at 46.5 °C density pentane 36.°C 1050. torr mL 0.63 ethanol 78 C 204. torr mL 0.79 Be sure your answer has 2 significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal
