Learning Objectives
1. Recall the concept of atomic mass (from 1.2) and understand how this relates to molecular weight.
2. Use molecular weight to calculate the mass of molar solutions.

Note that you will require your Periodic table from 1.1 for this topic.

Questions:
1. What is atomic mass?
2. How does atomic mass relate to molecular weight?
3. Calculate the mass of sodium hydroxide would be required to make a 1M solution? Show your working out.
4. Calculate the mass of magnesium chloride would be required to make a 0.5M solution? Show your working out.
