Chemistry is essentially a series of conversions. Most problems follow a "A →right arrow →right arrow

If you are moving from one substance to another (e.g., from Reactant A to Product B), use the coefficients from the balanced equation. 3. Setup and Execution

Ensure your answer reflects the precision of the data you were given.

Set up your conversion factors so that units cancel out diagonally.

Does the problem mention "STP" or a specific gas? You might need the Ideal Gas Constant ( ) or molar masses from the periodic table. 2. Map the Path (Dimensional Analysis)

For gas laws or calorimetry, a quick sketch of the container or system can help you visualize which way energy or particles are moving.
