To determine the mass of the precipitate formed, we first need to identify the reaction taking place. The reaction between silver nitrate AgNO3 and potassium chloride KCl is a double displacement reaction, which forms silver chloride AgCl as a precipitate and potassium nitrate KNO3 in solution:AgNO3 aq + KCl aq AgCl s + KNO3 aq Next, we need to determine the limiting reactant. We can do this by calculating the moles of each reactant and comparing their mole ratios.Moles of AgNO3 = volume concentration = 50 mL 0.2 M = 10 mmolMoles of KCl = volume concentration = 75 mL 0.1 M = 7.5 mmolThe stoichiometry of the reaction is 1:1, so we can see that KCl is the limiting reactant.Now, we can calculate the moles of AgCl formed, which will be equal to the moles of the limiting reactant KCl :Moles of AgCl = 7.5 mmolTo find the mass of the precipitate, we need to convert moles of AgCl to grams using the molar mass of AgCl 143.32 g/mol :Mass of AgCl = moles molar mass = 7.5 mmol 143.32 g/mol = 1074.9 mgSo, the mass of the precipitate formed is 1074.9 mg.To calculate the percent yield, we need to know the theoretical yield and the actual yield. In this case, we don't have information about the actual yield, so we cannot calculate the percent yield. If the actual yield was provided, the percent yield could be calculated using the formula:Percent yield = actual yield / theoretical yield 100%
