Answer:
Moles of magnesium chloride can be produced are 0.2 moles
Step-by-step explanation:
The reaction of Mg with Cl2 is:
Mg + Cl₂ → MgCl₂
Where 1 mole of Mg reacts per mole of Cl₂ to produce MgCl₂.
As the reaction is 1:1, we need to convert the mass of both Mg and Cl₂ to moles. The lower number of moles will determine the moles of MgCl₂ that will be produced:
Moles Mg -Molar mass: 24.3g/mol-:
4.86g * (1mol / 24.3g) = 0.2 moles Mg
Moles Cl₂ -Molar mass: 24.3g/mol-:
21.27g * (1mol / 70.9g) = 0.3 moles Cl₂
As moles of Mg < moles of Cl₂, Mg is limiting reactant and moles of magnesium chloride can be produced are 0.2 moles
