Problem-1 Citric acid, H3C6H5O7, is a weak organic acid that occurs naturally in plants. The acid is added to beverages and candy. An aqueous solution is 0.688m citric acid. The density is 1.049g/mL. Calculate: i) the molarity of the solution 0.688mH3C6H5On=0.68O weves H3C6H5O7 ii) the freezing point of the solution. Given Kf=1.86C/m Tsolin =0C(1.86)(0.60)(0.6.88) Tsolm= FP =0.7608 iii) the boiling point of the solution. Given Kb=0.512C/m T301x=100C+(1.86)(0.60)(0.688) iv) the osmotic pressure of the solution @23C. Given: R=0.08206L.atm /molK (0.60)(k0.08206kx+x)(2733.15+20) v) the mole fraction of citric acid vi) the mass percent of citric acid
