00:01 Question 98 from chapter 13 and we have to find a total vapor pressure of two liquids.
00:06 So for this question, we're going to be using row which roll.
00:13 And so the first thing we have to do for a is fine b -mo fraction.
00:21 And so we have one more of a and one more of b.
00:25 So we have two total.
00:28 So which means the a fraction is 1 over 2, which is equal to 0 .5...
