One of the first types of questions you'll encounter working with moles is determining the relationship between number of atoms in a compound and the number of moles. Here's a typical chemistry homework problem:

Question: How many moles of carbon (C) atoms are in 1 mol of table sugar (sucrose)?

Answer: The chemical formula of sucrose is C12H22O11, which means 1 mole (mol) of sucrose contains 12 moles of carbon atoms, 22 moles of hydrogen atoms, and 11 moles of oxygen atoms. When you say "1 mol sucrose", it's the same as saying 1 mole of sucrose atoms, so there are Avogadro's number of atoms in one mole of sucrose (or carbon or anything measured in moles).

There are 12 moles of C atoms in 1 mol of sucrose.
