A 6.67 grams sample of potato chips was blended with water and filtered. Excess silver nitrate solution was added. The dried precipitate had a mass of 0.245 grams. Calculate the percentage by mass of salt in the potato chips.
Help, anyone? I don't know how to answer this

silver chloride would precipitate from the reaction
thus find the mol ratio of the silver chloride to the NaCl
then plug in the amount of mols of the silver chloride (the precipitate mass/ molar mass of the silver chloride)
to get the amount of mols of salt
multiply by the molar mass of salt
then divide by the total mass of the chip (6.67g) to get ur answer
pls choose this as the best answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!… i need the points!!!!
