High School Chemistry explores the fundamental principles of chemistry, including the structure of atoms, chemical reactions, and the properties of matter.
Chemistry involves plenty of calculations, from balancing equations to finding molar mass. Practice solving problems step by step and double-check your work. Use units throughout your calculations to avoid mistakes. If you get stuck, break the problem into smaller pieces and look for similar examples in your notes or textbook.
Write out all units when converting grams to moles, so you don't lose track of what you're measuring.
If a calculation doesn't work out, check to see if you balanced the equation correctly first.
