Common Pitfalls

1. Forgetting to balance equations before performing calculations — always check that atoms and charges balance on both sides.

2. Forgetting to convert between units (e.g., $\text{cm}^3$ to $\text{dm}^3$) when calculating concentrations.

3. Drawing structural formulae incorrectly — check the number of bonds each atom can form and the overall charge.

4. Confusing the terms ‘molar’ and ‘molecular’ — molar refers to per mole ($\text{mol}^{-1}$), while molecular refers to individual molecules.
