Study Notes
Gas Law Stoichiometry
- Gas law stoichiometry is the same as other stoichiometry.
- It involves three steps:
- Convert to moles
- Convert moles of known to moles of unknown
- Convert to desired unit
- The ideal gas law provides a different way to convert to moles for any gas conditions, not just standard temperature and pressure (STP).
Summary of SCH3U0 Units (Converting to/from Moles)
- Using: Particles, Mass, Volume (Solutions), Volume, Pressure, Temperature (Gases)
- Unit-Conversion Factor/Method:
- Particles: Avogadro's number (6.022 x 1023 particles/mol)
- Mass: Molar mass (g/mol)
- Volume (Solutions): Concentration (mol/L)
- Volume, Pressure, Temperature (Gases): PV = nRT
Example 1: Nitrogen and Hydrogen Reaction
- Nitrogen (N2) gas reacts with hydrogen (H2) gas to form ammonia (NH3).
- If 1.00 L of N2 reacts with excess hydrogen under standard ambient temperature and pressure (SATP), the volume of ammonia produced is 2.00 L.
- The volume ratio follows the mole ratio for gases in a reaction.
Example 2: Iron and Sulfuric Acid Reaction
- What volume of hydrogen gas is produced when 40.0 g of iron reacts with excess sulfuric acid at 18.0 °C and 100.3 kPa?
- Given parameters are iron mass (40.0 g), temperature (18.0°C), and pressure (100.3 kPa).
- The required reaction is provided: Fe(s) + H2SO4(aq) → H2(g) + FeSO4(aq)
- The calculation steps (likely using the ideal gas law) and the final volume of hydrogen gas produced are needed to complete the answer.
