Question

1,15g of a non-volatile compound is dissolved in 75,0g of benzene. The boiling point of the solution 0,125ºC has a value greater than the corresponding pure benzene. Calculate the molecular weight of the compound.

Answer 1

I think you need to re-word the question. I find it difficult to believe that a solution boiling at 0.125C is greater than that of pure benzene. Do you know the b.p. of pure benzene. I think it's about 80 C.
