The density of Toluene (C7H8) is .867 g/mL, and the density o thiophene (C4H4S) is 1.065 g/mL. A solution is made by dissolving 10.5 g of thiophene in 250 mL of Toluene.
A)Calculate the mole fraction of the thiophene in the solution.
B)Calculate the molality ofthe thiophene in the solution.
C)Assuming that the volumes of the solute and solvent are additive, what is the molarity of thiophene in the solution?
