How to Master General Chemistry Stoichiometry for the DAT

If you're preparing for the DAT, you’ve likely hit a wall at least once trying to balance chemical equations or convert between moles and grams. Stoichiometry isn’t just a fundamental chemistry concept—it’s a must-know for test day.

Today, I’m going to break it down and show you how to master stoichiometry for the DAT, using proven strategies and one of King of the Curve’s signature visuals to help you learn fast and retain even faster.

🔬 What Is Stoichiometry and Why It Matters on the DAT

Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. On the DAT, stoichiometry questions are:

• Fast-paced

• Heavily calculation-based

• Often appear with limiting reagents or percent yield

You’ll typically see 2–3 stoichiometry questions in the General Chemistry section of the DAT. That’s a lot of points on the line!

The Four Steps:

1. Balance the equation

2. Convert known quantities to moles

3. Use mole ratios to determine unknowns

4. Convert moles back to desired units (grams, volume, etc.)

🧠 Pro Tip: Use dimensional analysis every single time—it will prevent silly mistakes under pressure.

💥 Common DAT Stoichiometry Question Types

1. Limiting Reagent Problems

   • Know how to compare moles of each reactant

2. Percent Yield

   • Use actual/theoretical × 100%

3. Mole-to-Mass Conversions

   • Understand molar mass + Avogadro’s number

4. Gas Stoichiometry at STP

   • 1 mol = 22.4 L (at standard temp and pressure)
