For the reactions shown below, we added 2.25 mL of 0.0540 M HCl to a test tube containing one of the two cations (Ag⁺ or Pb²⁺) and recovered 0.0174 g of precipitate.

AgNO₃(aq) + HCl(aq) → AgCl(s) + HNO₃(aq)
Pb(NO₃)₂(aq) + 2 HCl(aq) → PbCl₂(s) + 2 HNO₃(aq)

How much precipitate in moles would be recovered theoretically if the ion was Ag⁺? (Enter an unrounded value. Use at least one more digit than given.) (in mol)

How much precipitate in moles would be recovered theoretically if the ion was Pb²⁺? (Enter an unrounded value. Use at least one more digit than given.) (in mol)

How much precipitate in grams would be recovered theoretically if the ion was Ag⁺? (in g)

How much precipitate in grams would be recovered theoretically if the ion was Pb²⁺? (in g)

Based on the precipitate amount recovered, which of the two ions was in the unknown? Ag⁺ OR Pb²⁺
