Problem

Neurotransmitters are molecules that are released by nerve cells to other cells in our bodies, and are needed for muscle motion, thinking, feeling, and memory. Dopamine is a common neurotransmitter in the human brain.

The structure of benzene is a six-carbon hexagon arranged with its points up and down.  The sides of the hexagon are alternating double and single bonds, with the left side being the first double bond.  The top and bottom point and lower right vertex are all single bonded to H.  The upper and lower left vertices are single bonded to OH.  The upper right vertex is single bonded to C, which is single bonded above and below to H and right to C.  That C is single bonded above and below to H and right to N, which is single bonded to two Hs.

Patients with Parkinsons disease suffer from a shortage of dopamine and may need to take it to reduce symptoms. An IV (intravenous fluid) bag is filled with a solution that contains 400.0 mg dopamine per 250.0 mL of solution. What is the concentration of dopamine in the IV bag in units of molarity?
