Answer:

C) 6.95 M.

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:

[tex]M=\frac{n_{solute}}{V_{solution}}[/tex]

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

[tex]M=\frac{0.660mol}{0.0950L} \\\\M=6.95 M[/tex]

Therefore, answer is C) 6.95M.

Best regards.
