Name the three pieces of apparatus shown.
Enter the figures into the results table. Complete the results table for titrations $1$, $3$ and $4$.
Tick (✓) the best titration results in the table. Use these best titration results to calculate the average volume of $0.600\,\text{mol dm}^{-3}$ hydrochloric acid used.
Suggest why the volume of distilled water the student adds to apparatus A does not affect the results of the titrations.
Calculate the number of moles of $0.600\,\text{mol dm}^{-3}$ hydrochloric acid used by this second student.
Calculate the number of moles of magnesium hydroxide present in $5.0\,\text{cm}^3$ of the Milk of Magnesia.
Calculate the mass of magnesium hydroxide in $5.0\,\text{cm}^3$ of the Milk of Magnesia. [$A_r$: Mg, $24$; O, $16$; H, $1$]
The density of the Milk of Magnesia is $2.34\,\text{g cm}^{-3}$. $\text{density in g/cm}^3 = \frac{\text{mass in g}}{\text{volume in cm}^3}$. Calculate the mass of $5.0\,\text{cm}^3$ of the Milk of Magnesia.
Calculate the percentage by mass of magnesium hydroxide in the Milk of Magnesia.
