Step 1

Given that,

Vapor pressure of pure heptane = 0.50 atm

Mass of heptane = 110.0 g

Mass of Chloroform = 133.0 g

Step 2

Now, you calculate the no.of mole of heptane help_outlineImage TranscriptioncloseGiven mass No.of moles= molecular mass 110.0g No.of moles of heptane=- 100.21 mole =1.098 moles 133.0g No.of moles of chloroform- 119.38 mole =1.114 mole fullscreen
