The vapor above a mixture of pentane and hexane at room temperature contains 35.5% pentane by mass. What is the mass percent composition of the solution? Pure pentane and hexane have vapor pressures of 425 torr and 151 torr, respectively, at room temperature.
And we have to answer two questions:
1) What is the mass percent of C5H12?
2) What is the mass percent of C6H14?
Trust me, I have attempted this problem three different times! I don't want to put it up here because I just get more confused thinking through what I did, and it will probably confuse people, too. While I wait for a response, I will keep trying, too. Thank you SO MUCh!!
