A solution of toluene (also called 1-methylbenzene) in benzene is prepared. The mole fraction of toluene in the
solution is 0.100. What is the molality of the solution?
I tried working with 1 mol toulene. I got 1 mol toulene/9 mol h20. 1 mol toulene/0.162 kg = 6.2molal.
But the answer is wrong, where did I screw up?
