Question 13

Medium

A group of researchers investigated the industrial electrolysis of molten magnesium chloride using inert carbon electrodes. They recorded the mass of magnesium metal produced at the cathode over time under different constant currents. The results of their investigation are plotted on the graph below:

Electrolysis of Molten Magnesium Chloride Graph

Determine the number of magnesium atoms produced when the molten magnesium chloride is electrolysed for $minutes45\text{ minutes}$ at a current of $A1.5\text{ A}$ .

Give your answer to $3$ significant figures.

Relative atomic mass ( $A_r$ ): $Mg=24.0\text{Mg} = 24.0$ .

The Avogadro constant = $6.02 \times 10^{23}$ per mole.
