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.
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?
We have to calculate the molarity of solution inside an IV bag that contains 400.0 mg dopamine per 250.0 mL of solution.
Molarity is calculated by this formula:
The number of moles of the solute can be calculated by this formula:
