1. Write the balanced chemical equation:
Zn(s) + 2Pb(SO₄)₂(aq) → Zn(SO₄)₂(aq) + 2PbSO₄(s)
2. Determine the mole ratio:
The balanced equation shows that 1 mole of zinc (Zn) reacts to produce 2 moles of lead(II) sulfate (PbSO₄).
3. Calculate the moles of lead(II) sulfate produced:
Since we have 0.320 moles of zinc, and the mole ratio is 1:2, we will produce:
0.320 moles Zn * (2 moles PbSO₄ / 1 mole Zn) = 0.640 moles PbSO₄
4. Calculate the mass of lead(II) sulfate produced:
To convert moles of PbSO₄ to grams, we need the molar mass of PbSO₄:
* Pb: 207.2 g/mol
* S: 32.06 g/mol
* O: 16.00 g/mol (x 4)
Molar mass of PbSO₄ = 207.2 + 32.06 + (16.00 * 4) = 303.26 g/mol
Now, calculate the mass:
0.640 moles PbSO₄ * (303.26 g PbSO₄ / 1 mole PbSO₄) = 194.1 g PbSO₄
Therefore, 194.1 grams of lead(II) sulfate would be produced.
