Chapter 14, Problem 92IAE

Suppose you have available 2.50 L of a solution (d = 0.9767 g/mL) that is 138% ethanol ( ${\text{CH}}_{\text{1}}{\text{CH}}_{\text{2}}\text{OH}$ ), by mass From this solution you would like to make the maximum quantity of ethanol-water antifreeze solution that that offer protection to $\text{-20}°\text{C}$ Would you add more ethanol or more water to the solution 7 What mass of liquid would you add?
