Before 1962,dimes minted in the US contained the precious metal silver.A 2.08 gram dime is dissolved in nitric acid and reacted with saturated sodium chloride solution. This process precipitates all the silver in the dime as 342mg of AgCl(s). How many moles of silver did the dime contain?

Answer 1

molar mass of silver chloride, AgCl = 143.32
No. of moles of silver chloride
= no. of moles of silver
= 0.342 g/ 143.32 g/mol
= 0.00239 mole
