Fred wanted to reclaim silver from metal waste (iron, copper, nickle, and silver) reclaimed from teh floor of a jewelry shop. He dissolved 159.7 g of the metal waste in nitric acid and then diluted it with water. he then added 10 mL concentrated HCL and precipitated all the silver as the chloride. Upon filtration and drying, he had 42.729g of precipitate. calculate the amount of pure silver in w/w% of the original sample.

an atomic unit is definedas exactly [one of the following]:
1) 1/14 the mass of a 14N atom
2) 1/12 the mass of a 12C atom
3) 1/19 the mass of a 19F atom
4) 1/16 the mass of a 16O atom

(the 1/14, 1/12 and so on are fractions)
(the number in 14N, 12C, and so on are supposed to be small and written at the top [like exponents i guess])

whats the answer?
please and thanks
