I have the 2008 version so i am not sure if the question numbers will be same.
The question asks
at 0 degrees celsius a gas is dissolved in H2o at a mole fraction of 2x10^-18. What is the molality of the solution given the molecular wt of the gas is 32g/mol
a. 5x10^-4
b. 1x10^-14
c.1x10^-16
d.1x10^-12
e. 4x10^-7
I see the solution in the back but i have no clue why they assumed 1 mole of water????
