A lovely challenge to get students thinking about what concentration means.
At basic levels the expt can be used to determine which acid is the more concentrated (Mg reacts more quickly)
On the higher level you can use the apparatus suggested to calculate pretty much how much more concentrated one is than the other (determined by you) but calculated by the ratio of the times taken to react equal amounts of Mg
