By the end you’ll be able to

calculate concentration in $\text{mol dm}^{-3}$ using $c = \dfrac{n}{V}$ with volume in $\text{dm}^3$
convert volumes between $\text{cm}^3$ and $\text{dm}^3$ and use these units correctly in calculations
calculate the amount of solute in a given volume of solution and calculate required volume from concentration and moles
