1 Molar Concentration: The molarity (or molar concentration) is defined as: \(c = \frac{n}{V}\)

\(c\) is the concentration of the solution in mol/L, \(V\) is the volume of the solution in L, and \(n\) is the amount of the solute in mol.

For example, suppose we dissolve 15.0g of NaOH and create 225mL of solution. The molarity (or molar concentration) of the solution is given by:

\(c = \frac{15.0\text{g} \cdot \frac{1\text{mol}}{40.0\text{g}}} {0.225\text{L}} = 1.67 \text{mol/L}\)

where \(\frac{1\text{mol}}{40.0\text{g}}\) is the mol/g for NaOH.

2 Tasks: Either in another class, or in one of the existing classes, implement one or more methods that can be used to calculate any of \(c\), \(n\) or \(v\) from the other two. (Note: You should spend a considerable amount of time thinking about which classes the methods should belong to and whether they should be static or not.)
