Calculate the mass of oxalic acid crystals that were used in the experiment.
Name the apparatus in which solution $H$ is to be made up to $500\,\text{cm}^3$.
Name the apparatus used for transferring $25.0\,\text{cm}^3$ of $H$ into the conical flask.
What colour is the solution in the conical flask when $G$ has just become in excess?
Use the diagrams to fill in the titration table and find the average volume of $G$.
Calculate the number of moles of potassium manganate(VII) in the average volume of $G$ used in (d).
Deduce the number of moles of oxalic acid crystals present in $25.0\,\text{cm}^3$ of $H$.
Deduce the number of moles of oxalic acid crystals in $500\,\text{cm}^3$ of $H$.
Use your answers to (a) and (g) to calculate the relative formula mass of oxalic acid crystals.
Oxalic acid crystals consist of water and oxalic acid, $\text{H}_2\text{C}_2\text{O}_4$. Use your answer to (h) to calculate the percentage by mass of water in oxalic acid crystals.
