- Read chemical notation and identify known quantities
- Explain a calculation before substituting numbers
- Check units, signs and whether the result is plausible

Practice before your session
Original study example
Dissolve 0.10 mol of a substance to make 0.50 L of solution. Find the concentration and explain what changes if the final volume doubles.
Work through the example
Concentration is amount divided by volume: 0.10 / 0.50 = 0.20 mol/L. At 1.00 L with the same amount, it becomes 0.10 mol/L. Write the units at every step and distinguish changing volume from changing the amount.
What to bring for CHEM 209
- Bring the current outline for CHEM 209, your university and the chapter you are studying.
- Choose one chemistry question you have attempted and mark the first step you cannot explain.
- Include your deadline, preferred format and any tools or notation required by your instructor.

Will the example match my exam or assignment?
This original example illustrates a study method. Share your own outline and attempted question so the team can confirm the right support. It is not a university exam question or a prediction of your assessment.
