Explanation:
Answer:
100. mL
Explanation:
Step 1: Write the balanced equation for the double displacement reaction
CaCl₂ + Na₂CO₃ ⇒ 2 NaCl + CaCO₃
Step 2: Calculate the moles corresponding to 1.00 g of CaCO₃
The molar mass of CaCO₃ is 100.09 g/mol.
1.00 g × 1 mol/100.09 g = 0.0100 mol
Step 3: Calculate the moles of CaCl₂ required to produce 0.0100 moles of CaCO₃
The molar ratio of CaCl₂ to CaCO₃ is 1:1. The moles of CaCl₂ required are 1/1 × 0.0100 mol = 0.0100 mol.
Step 4: Calculate the volume of 0.100 M CaCl₂ that contains 0.0100 mol
0.0100 mol × 1 L/0.100 mol × 1000 mL/1 L = 100. mL
