A solution is prepared by dissolving 18g of water in 150g of glucose,the resulting solution was found to have boiling point of 100.34°c. Calculate the molar mass of glucose.

Answer 1

I know the boiling point constant for H2O (0.512 degreed C/molal) but not for glucose; therefore, my assumption is that you are dissolving the glucose in the water and not the other way. In addition, I do not believe your numbers are right. I think you meant that you were dissolving 18 g glucose in 150 g water.
Please correct your problem. You SHOULD proof before you publish.

Answer 2

Very good
