Answer:

0.82 M

Explanation:

You have been given moles and volume (in mL). To find the molarity of the solution, you need to (1) convert mL to L and then (2) plug moles and volume into the molarity formula.

985 mL / 1,000 = 0.985 L

Molarity (M) = moles / volume (L)

Molarity = 0.81 moles / 0.985 L

Molarity = 0.82 M
