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".
