An industrial lab technician wants to prepare a stock solution of iron(III) sulfate so that when 50.00 mL is diluted to 1.000 L, the diluted solution will
have a concentration of 0.030 M. What should the concentration of the
stock solution be?

You know how the first one if filled up like the objects do the same but with the other categories

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

Ithink its solid. hope this
