Problem- The density of toluene (C7H8) is 0.867g/mL, and the density of thiophene (C4H4S) is 1.065 g/mL. A solution is made by dissolving 8.80g of thiophene in 270mL of toluene.
Part A
Calculate the mole fraction of thiophene in the solution.
mole fraction of C4H4S =
molality of C4H4S =
Assuming that the volumes of the solute and solvent are additive, what is the molarity of thiophene in the solution?
Not confident which formulas/units I require to solve something like this
