i have 0.112 mol of bromo, and 0.732 mol chloro, but i am stuck on the mole fraction. Do i just do 1-0.112= 0.888 or am i missing a step?

ok, this is what I have. Xbromo= 0.112/+0.732+0.112=0.133 Xchloro= 1-0.133= 0.867 P=Xbromo*p= 0.133*137= 18.221mmHg P=Xchloro*p= 0.867*285= 247.095mmHg so I add 18.221+247.095= 265.316mmHg Is that right?

how do i get the mole fraction?

thats what i did and i got it wrong. my answer was 53.46. the study guide says 54.2.

the molality possibly should have been molarity. i am getting the two confused at the moment. this is a revision question in my topic on solutions.

so, 0.68K/6.8 K kg mol= 0.1kg/mol (m) then 0.1/32g/mol= 3.1*10^-3 then (3.1*10^-3)*(2.56g)= 8*10^-3 does that make it S8, i don't get that part.

POS= 1/2 of 82, so 10x+1= 42. You can do that. A bisector splits something into 2 equal halves. If you can't get it , draw a picture, it helps. if you are in Geometry, go to you tube videos and watch yay math videos. They saved me last year.

Sorry, I meant half of 82.. so in 10x+1=41. Anyway, x= 10. Hope I caught you in time.
