Over #8# #mol*L^-1#.

Explanation:

I am surprised that this question did not give a mass of barium chloride, and ask you to calculate the molar quantity for the concentration expression.

Anyway, #"Concentration"# #=# #"Moles of solute (moles)"/"Volume of solution (Litres)"# #=# #(7.1*mol)/(0.85*L)# #=# #??*mol*L^-1#

The given concentration is with respect to #"moles of barium sulfate per litre"#.
