The potato chips are seasoned with table salt, NaCl. You weigh out a handful of the chips, boil them in water to extract the salt, and then filter the boiled chips to remove the soggy chip pieces. You then analyze the chip filtrate for Cl- concentration using the Mohr method.First you prepare a solution of silver nitrate, AGNO3, and titrate it against 0.500 g of KCl using the Mohr method. You find that it takes 64.5 mL of AgNO3 titrant to reach the equivalence point of the reaction. You then use the same silver nitrate solution to analyze the chip filtrate in a Mohr reaction, finding that the solution yields a rusty brown precipitate when 45.4 mL of titrant is added. Part A If the sample of chips used to make the filtrate weighed 76.5 g , how much NaCl is present in one serving (105 g ) of chips?…Ssolve asap like is ready pls pls solve fast
