3)Trimellitic acid has an empirical formula C3H2O2. A 2.416 g sample of trimellitic acid was dissolves in 40.00 g of propanone, producing a solution that boils at 56.46 C. Kb for propanone is 1.71 C/molal.Pure propanone has a boiling point of 56.20 C.

i)What is the molality of the propanone solution?

ii)How many moles of trimellitic acid are in the 40.00 g of propanone?

iii)What is molecular weight of trimellitic acid?

iv)What is molecular formula for trimellitic acid?

 

 

2)a concentrated sulfuric acid solutioin is 74.0% H2SO4 by mass and has a density of 1.66 g/ml.at 20C

i) What is the molality of the sulfuric acid solution?

 

 

ii) What is the molarity of the sulfuric acid solution?
