1. Write the balanced chemical equation:
AgNO₃(aq) + HCl(aq) → AgCl(s) + HNO₃(aq)
2. Determine the moles of AgNO₃:
* Molarity (M) = moles (mol) / volume (L)
* 0.068 M = moles / 0.025 L
* moles of AgNO₃ = 0.0017 mol
3. Use the mole ratio from the balanced equation to find moles of AgCl:
* The balanced equation shows a 1:1 mole ratio between AgNO₃ and AgCl. Therefore, 0.0017 moles of AgNO₃ will produce 0.0017 moles of AgCl.
4. Calculate the mass of AgCl:
* Molar mass of AgCl = 143.32 g/mol
* mass = moles x molar mass
* mass of AgCl = 0.0017 mol x 143.32 g/mol
* mass of AgCl = 0.244 g
Therefore, 0.244 g of solid AgCl is obtained.
