Bonjour, pouvez vous m’aider avec ces questions, surtout la deuxième svp ?

You want to break down a piece of magnesium Mg (s) with
mass m=7.3 g. For this, place it in an Erlenmeyer flask with
a solution of zinc sulphate (Zn²+ (aq) + SO2 (aq)) with an
amount-of-substance concentration c=5.0 x 102 mol -L-1
The equation modelling the transformation is:
Mg (s) +Zn²+ (aq) → Mg2+ (aq) +Zn (s).
Data: M-24.3 g-mot¹.
1. Make a progress chart.
2. Deduce the volume V of zinc sulphate to mix with the
magnesium to make it disappear entirely.
