Chemistry Formula Practice

How to use this set

Treat every problem as if it were an AP Exam FRQ. Each formula includes three practice questions (simple, unit conversion, and multi-step). When you are ready, expand a problem to check your answer, or jump to the full explanation PDF below.

• Show all work — write out every step, include all units (even when substituting values into formulas), and present your final answer in context with correct units and significant figures.
• Use pen and paper — work on a separate sheet of paper (preferably one page per question) using black or blue ink.
• Avoid iPads — writing on a tablet is not as effective and is not how AP Exams are conducted.
• Do NOT use a keyboard and mouse — handwriting your solutions builds the skills you will need on exam day.
