. How many grams of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide? Cl2 + MgBr2  ___MgCl2 + ___Br2

190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.

Explanation:

The balanced chemical reaction is;

is the limiting reagent as it limits the formation of product and is the excess reagent.

According to stoichiometry :

1 mole of produces = 1 mole of

Thus 2 moles of will produce=  of

 Mass of

Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide
