Mole Concept
0.50 mol of CaCO3 is heated strongly. How many liters of CO2 (at STP) are evolved? (CaCO3 → CaO + CO2)
Select the correct option:
Solution
11.2 L
- Reaction Balance: CaCO3(s)ΔCaO(s)+CO2(g).
- Stoichiometry: 1 mol CaCO3 produces 1 mol CO2.
- Calculate Moles CO2: 0.50 mol CaCO3→0.50 mol CO2.
- Convert to Volume at STP:
- Volume=Moles×22.4 L
- Volume=0.50×22.4=11.2 L.
