Error in solutions manual 10.109

Postby Kayla Denton 1A » Sat Jan 31, 2015 5:48 pm

Hi! I believe there is an error in the solutions manual for question 10.109 part b. The vapour pressure of bromine is correctly calculated as 0.285 bar, but the textbook converts this to 0.289 atm. However, 1 bar = 0.9869... atm so the correct conversion should give 0.281 atm rather than 0.289.

(For part d, then, the answer should be 870 mL rather than 846.)

I got the same answers as Kayla.

Also, for part c of this problem, the solutions manual shows that PBr(g)2=3.6x10-15 bar, but this is the answer for just the partial pressure, PBr(g), not the partial pressure squared.

Well done Kayla and Niharika.
Niharika we have met before, but both of you should come introduce yourselves at the end of class.
