Comprehensive Gas Laws Reference Sheet for Chemistry Students

- Identify the relevant gas law based on the variables given and what is being solved for (e.g., Boyle’s Law for P and V at constant T, Charles’s Law for V and T at constant P, Combined Gas Law for changes in P, V, and T).
- Ensure all temperatures are converted to Kelvin using K = °C + 273.15.
- Convert all pressure units to be consistent (e.g., atm, kPa, mm Hg) using the provided conversion factors (1 atm = 760 mm Hg = 101.325 kPa).
- Convert all volume units to be consistent (e.g., L, mL, dm³) using the provided conversions (1 L = 1000 mL = 1 dm³).
- Plug the known values into the appropriate formula, making sure subscripts (1) and (2) correctly represent initial and final conditions.
- Solve algebraically for the unknown variable.
- Include correct units in the final answer and round to an appropriate number of significant figures based on the given data.
