Answer to Question #312317 in General Chemistry for Ivan Ackerman

Question

For the chemical reaction

Na2CO3+Ca(NO3)2⟶CaCO3+2NaNO3

how many moles of calcium carbonate (CaCO₃) are produced from 6.0 mol of sodium carbonate (Na₂CO₃)?

Answer 1

Solution:

Balanced chemical equation:

Na₂CO₃ + Ca(NO₃)₂ ⟶ CaCO₃ + 2NaNO₃

According to stoichiometry:

1 mol of Na₂CO₃ gives 1 mol of CaCO₃

Thus,

6 mol of Na₂CO₃ gives 6 mol of CaCO₃

Answer: 6 moles of calcium carbonate (CaCO₃) are produced
