Answer:

1) 7.256 mol Br2 (Cl2)/(Br2)

The Br2 cancels out, so we have 7.256(2)

This is 14.512.

2) Number of moles = mass / molar mass

Number of moles = 239.7 g/ 35.5 g/mol

Number of moles =  6.8 mol

BrCl=13.6 mol

13.6(11.5.357)

1568.9 g

3) Repeat the same process with problem 2, given that there are 6.022x10^23 atoms in a mole.

Explanation:

Br2 + Cl2 → 2BrCl
