A Fun Chemistry Problem to Solve!
How Much Calcium Carbonate Was Used?
A pure sample of calcium carbonate produced 0.998 g of CO2. What was the mass of the calcium carbonate used?
Answer:
The mass of the calcium carbonate used was 2.272 grams.
If you're curious about how we arrived at this answer, let's break it down step by step:
Step 1: Calculate the Molar Mass
The molar mass of calcium carbonate (CaCO3) is 100.1 g/mol and the molar mass of carbon dioxide (CO2) is 44.01 g/mol.
Step 2: Convert Mass of CO2 to Moles
0.998 g CO2 is equivalent to 0.0227 mol CO2.
Step 3: Use Stoichiometry
For every 1 mole of CaCO3, 1 mole of CO2 is produced according to the balanced chemical equation.
Step 4: Convert Moles of CaCO3 to Grams
0.0227 mol CaCO3 corresponds to 2.272 g of CaCO3.
And that's how we found out that the mass of the calcium carbonate used was 2.272 grams. Chemistry can be fun and rewarding when you solve these kinds of problems!
