NOrE: There are several steps in this problem. To avold WesAssign marking answers incarrect due to rounding-off emars, you should avold rounding aff your answers at each step while warking the. probiem, In other words: round each step to the correct number of significant digts for entering into WebAssign, but continue to use unmunded values (at least 2 mare digis than the rounded-off value, in your own cakulations. You Leve prepared a solution of 8.250g of magnesum bremide (MgBr, molar mass 184.11 g/mel) dissolved in 113mLof2 isopropanol (CH3CH2CHCH3. molar mass so. 69 gimol). At 20C, the isoprosanol has a denaity of 0.735a/mL and a vapor pressure of 4.32kPa. (a) What is the van 't Hof factor of the solute? [DP (b) Assuming the solute Aufy dissociates in the selvent, what wit be the total number of moles of solute particies in this solution? [ul (c) How many moles of solvent are used in this solution? (Assume the solution was prepared at 20C ) IID) (d) Calculate the total number of moles of solute partides and solvent molecules in this solution: moles (e) Calculate the mole fraction of solvent in this solution: solv = TDP (i) Now finaly, determine the vaoor pressure of the solubon at 20C ETD) kPa
