How do I answer this

A coin 5.00g contains silver. The coin is dissolved in 500cm^3 of concentrated nitric acid to for AgNO3

50.0cm^3 of this solution is reacted with excess sodium chloride solution to form a precipitate of silver chloride AgCl

AgCl^+ + Cl- -> AgCl

After filtering and drying the mass of the precipitate was 0.617g

Calculate the percentage mass of silver in the

What have you tried, so far?

There are lots of numbers there, what have you tried to do with them?

I ended up skipping this question as I couldn’t find a place to start. I tried using the concentration formula however I wasn’t sure if it would work. Any advice as to where I could start?

Start with the final mass and work backwards through the Q.

It is commonly the way you do chemistry Qs.
