Stoichiometry



Summary
The content provides a foundational understanding of key concepts in general chemistry relevant for the MCAT, focusing on stoichiometry, kinetics, equilibrium, and LeChatelier's Principle.
  • Empirical and molecular formulas represent the composition of compounds, with empirical formulas showing the simplest ratio and molecular formulas showing actual atom counts.
  • The concept of a mole is introduced as a fundamental unit of measure in chemistry, essential for quantifying substances.
  • Equivalents are used to describe the number of moles of a specific atom within a mole of a compound, particularly in the context of acids.
  • Conversion between mass and moles is facilitated by the molecular weight, allowing for calculations of substance quantities in reactions.
  • Stoichiometry is described as the measurement of elements to determine compound compositions and reaction products, including methods to calculate percent composition and yield.
