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

Step-by-step explanation:

The balanced chemical reaction is;


Cl_2+MgBr_2\rightarrow MgCl_2+Br_2


Cl_2 is the limiting reagent as it limits the formation of product and
MgBr_2 is the excess reagent.

According to stoichiometry :

1 mole of
Cl_2 produces = 1 mole of
MgCl_2

Thus 2 moles of
Cl_2 will produce=
(1)/(1)* 2=2moles of
MgCl_2

Mass of
MgCl_2=moles* {\text {Molar mass}}=2moles* 95g/mol=190g

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