Mole Conversions Practice: 60 Problems

60 mole conversion practice problems for high school chemistry, with a one-page answer key. Pure practice: molar mass, grams, moles, particles and atoms inside compounds.

What’s inside

• Part A (10): molar mass
• Part B (20): grams ↔ moles
• Part C (10): moles ↔ particles (Avogadro’s number)
• Part D (10): grams ↔ particles
• Part E (10): atoms inside a compound
• Reference page: mole map, atomic masses, which particle to count
• One-page answer key, rounded to the correct significant figures
• Student progress tracker

Great for

• Homework and independent practice
• Review before a quiz or test
• Sub plans and early finishers

No notes and no long solutions, just plenty of problems and the final answers so students can check themselves. Textbook-style layout that prints well in black and white. Made by a chemist; every answer is calculated and checked.

Suitable for ages 14 to 18: high school chemistry (Grades 10–12) and international schools. Printable PDF.

Pairs with the “Molar Mass and Mole Conversion Worksheets” set (textbook-style notes and fully worked keys) in the Opalchemy shop.
