of silver nitrate is mixed with of calcium chloride. What mass of silver chloride precipitates? ( AgCl .)
Answer and explanation
Correct answer: B.
- Step 1: Moles mol. Moles mol.
- Step 2: is , so silver is the limiting ion and mol of AgCl forms.
- Step 3: Mass g.
Answer
.
Why not the others: : uses the chloride as the limiting ion, with mol of AgCl. : uses the moles of calcium chloride only. : halves the correct mass.
