Section 11.3: Stoichiometry of Gases
• Apply Gay-Lussac and Avogadro’s discoveries to the stoichiometry of reactions involving gases…
For gaseous reactants or products, the coefficients in chemical equations
reveal volume ratios (like mole ratios)
Volume-Volume Calculations• Example:
C3H8 + 5 O2 3 CO2 + 4 H2OIf the volume of propane combusted is 0.350 L….
What is the volume of CO2 produced?
