Based on the equation, how many grams of Br2 are required to react completely with 72.4 grams of AlCl3 NEVERMIND, I FIGURED IT OUT

 131 g of bromine is required.

Explanation:

The balanced equation will be :

To calculate the moles, we use the equation:

moles of

According to stoichiometry :

2 moles of require  = 3 moles of

Thus 0.544 moles of require=  of

Mass of

Thus 131 g of bromine is required.

hey your not cool]      

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.
