Chemistry is essentially a series of conversions. Most problems follow a "A →right arrow →right arrow
Ensure your answer reflects the precision of the data you were given. Solving General Chemistry Problems
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 Chemistry is essentially a series of conversions
In 90% of chemistry problems, the first step is converting your given mass or volume into moles . Moles are the universal currency of chemistry; once you have them, you can go anywhere. Many students understand the chemistry but lose points
Many students understand the chemistry but lose points on simple algebraic rearrangements. Rearrange your formula before plugging in the numbers.
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)
