MCAT CHEM4 Kaplan Review | 100+ Questions | Stoichiometry, Moles, Reactions, Yield, Equations

This expert-verified MCAT study guide offers 100+ flashcard-style Q&A based on Kaplan CHEM4 content, focusing on stoichiometry—a foundational chemistry topic for the MCAT Chemical and Physical Foundations section. It breaks down complex reaction math, formulas, and definitions with clarity and MCAT-style reasoning, making it a high-yield prep tool for pre-med students. Core topics include: Definitions and differences between molecular weight, molar mass, and gram equivalent weight (GEW) Understanding normality, equivalents, and molarity as they apply to acid-base and redox reactions Empirical vs molecular formulas, and calculation of percent composition Five major reaction types: combination, decomposition, combustion, displacement, and neutralization Step-by-step guide to balancing chemical equations based on atom type and charge conservation Core stoichiometric parameters: Limiting reagent and excess reagent identification Theoretical yield, actual yield, and percent yield Percent error and formula breakdown Rules for ion naming and charges: -ous vs -ic, -ite vs -ate, hypo-/per- prefixes monoatomic vs polyatomic ion naming patterns Charge trends: metals forming cations, nonmetals forming anions, solvation, and electrolyte strength Common equations to memorize: mol = mass / molar mass molarity = mol / volume percent composition = element mass / total mass equivalents from mass = mass / GEW GEW = total molar mass / n (moles of H+ or e⁻ involved) Perfect for: MCAT students mastering quantitative chemistry Coursework in General Chemistry, Analytical Chemistry, or Intro to Chemical Reactions Pre-med and life science majors preparing for lab-based exams Keywords: stoichiometry, molar mass, molecular weight, gram equivalent weight, limiting reagent, theoretical yield, actual yield, percent yield, percent error, empirical formula, molecular formula, reaction types, balancing equations, equivalents, normality, molarity, electrolytes, solvation, ion naming, chemical reactions, combustion, displacement, MCAT chemistry, Kaplan CHEM4
