A Solution Contains Pentane (C₅H₁₂, 72 $\degree$ C, Which Have Vapor Pressures of 511 and 150 Torr

Short Answer

A solution contains pentane (C₅H₁₂, 72.15 g/mol) and hexane (C₆H₁₄, 86.17 g/mol) at 25 $\degree$ C, which have vapor pressures of 511 and 150 torr, respectively.To create a solution with a total vapor pressure of 275 torr, approximately how many grams of hexane should be mixed with 50.0 g pentane?
