Methodology for Calculations

• To Calculate Moles: Moles = Mass (g) / Molar Mass (g/mol)
• To Find Mass from Moles: Mass = Moles × Molar Mass
• To Find Volume of Gas at STP: Volume = Moles × 22.4 L (for gases at standard temperature and pressure)
• To Identify Limiting Reagent:
  • Calculate moles of each reactant.
  • Use stoichiometric coefficients to determine which reactant will be consumed first.

Key Takeaways

• The Mole Concept is fundamental for understanding and performing chemical calculations.
• Mastery of Stoichiometry is crucial for success in chemistry exams.
• Practical examples and problem-solving techniques are essential for applying theoretical knowledge.
