Answer:

C) 6.95 M.

Step-by-step explanation:

Hello,

In this case, considering that the molarity is computed via the ratio of the moles of solute to the volume of the solution in liters:


M=(n_(solute))/(V_(solution))

Since the volume here is 95.0 mL or also 0.0950 L, the molarity turns out:


M=(0.660mol)/(0.0950L) \\\\M=6.95 M

Therefore, answer is C) 6.95M.

Best regards.
