Calculating concentration of product & mass of a precipitate

Click For Summary
SUMMARY

The discussion focuses on calculating the mass of calcium carbonate (CaCO3) precipitate and the concentration of sodium nitrate (Na3NO3) produced from mixing 100 mL of 0.2 mol/L sodium carbonate (Na2CO3) with 200 mL of 0.1 mol/L calcium nitrate (Ca(NO3)2). The balanced chemical equation is confirmed as 3Na2CO3 + Ca(NO3)2 → 3CaCO3 + 2Na3NO3. To find the mass of CaCO3, participants need to determine the moles of reactants and apply stoichiometry, ultimately converting moles to mass using the molar mass of CaCO3.

PREREQUISITES
  • Understanding of stoichiometry in chemical reactions
  • Knowledge of molarity and how to calculate moles from volume and concentration
  • Familiarity with balancing chemical equations
  • Ability to convert moles to mass using molar mass
NEXT STEPS
  • Calculate the moles of sodium carbonate and calcium nitrate present in the solutions
  • Determine the limiting reactant based on the balanced equation
  • Use the stoichiometric ratios to find the moles of calcium carbonate produced
  • Convert the moles of calcium carbonate to grams using its molar mass (100.09 g/mol)
USEFUL FOR

Chemistry students, educators, and professionals involved in chemical analysis or laboratory work, particularly those focusing on precipitation reactions and stoichiometric calculations.

The question is:
100 mL of 0.2 mol/L sodium carbonate solution and 200 mL of 0.1 mol/L calcium nitrate solution are mixed together. Calculate the mass of calcium carbonate that would precipitate and the concentration of the sodium nitrate solution that will be produced.

I believe the balanced equation would be: 3Na2CO3 + Ca3(NO3)2 ---> 3CaCO3 + 2Na3NO3
I'm not quite sure where to go from there. Please help!

There are a number of steps involved. A good idea is to write down what you know, what you don't know and how to obtain certain values (e.g. at the end, you need mass, how do you get mass from moles might be useful). Firstly, I am guessing it goes to completion? You know the number of moles that participates in a general reaction (3Na2CO3 + Ca3(NO3)2 ---> 3CaCO3 + 2Na3NO3), what does that tell you?
