An experiment similar to the one performed in this lab was carried out to determine the Ksp of PbCl2, The dissolved chloride in the filtered solution was quantitatively precipitated as AgCl by the addition of excess AgNO3 solution. The solid AgCl was filtered, dried, and weighed. The results were: Temperature of the solution = 20.2degreeC, Volume of PbCl2 solution analyzed = 24.40 mL, Mass of dry AgCl = 0.2991 grams. How many moles of AgCl were found? Enter your answer to the nearest 0.00001 mol.Explanation / Answer
mass of AgCl=0.2991g
moles of AgCl=0.2991g/143.5g/moles=0.002084moles
moles of Cl-=0.002084moles
moles of Pb2+=(moles of Cl-)/2=0.00104
