To solve this problem, we need to use the concept of stoichiometry and the balanced chemical equation to determine the amount of Zn(NO3)2 produced.Given information:- Balanced chemical equation: Zn + Pb(NO3)2 → Zn(NO3)2 + Pb- Mass of Zn: 34 g- Mass of Pb(NO3)2: 27 g- Mass of Pb produced: 12 gStep 1: Calculate the molar mass of each compound.Molar mass of Zn = 65.38 g/molMolar mass of Pb(NO3)2 = 331.21 g/molMolar mass of Zn(NO3)2 = 189.39 g/molMolar mass of Pb = 207.2 g/molStep 2: Calculate the number of moles of each compound.Moles of Zn = 34 g / 65.38 g/mol = 0.52 molMoles of Pb(NO3)2 = 27 g / 331.21 g/mol = 0.081 molStep 3: Determine the limiting reactant.Since the balanced equation shows that 1 mol of Zn reacts with 1 mol of Pb(NO3)2, the limiting reactant is Pb(NO3)2.Step 4: Calculate the amount of Zn(NO3)2 produced.Moles of Zn(NO3)2 produced = Moles of Pb(NO3)2 (limiting reactant) = 0.081 molMass of Zn(NO3)2 produced = Moles of Zn(NO3)2 × Molar mass of Zn(NO3)2Mass of Zn(NO3)2 produced = 0.081 mol × 189.39 g/mol = 15.36 gTherefore, the correct answer is:15.36 g
