Moles and Avogadro's constant (HT only)

This lesson, students will use the equation mass = relative formula mass x moles to find any one value when given the other two. Students will use Avogadro's constant to calculate the number of atoms/molecules in a given mass and also calculate the mass of a given number of atoms.
