Question: how many c atoms are in 1 mol of sucrose (c12h22o11)?
Answer: When you are talking about 1 mole of 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 mole of sucrose.
