An EpiPen, used to treat anaphalactic allergic reactions, contains 0.30 mg of epinephrine. The concentration of epinephrine in each syringe is 1.0 mg/mL. What is the volume, in milliliters (mL), of solution in each syringe

Respuesta :

Answer:

0.3mL

Explanation:

Mass = 0.30mg

Concentration = 1.0 mg/mL

Volume = x

The relationship between the three parameters is given as;

Concentration = Mass / Volume

Making Volume our subject of interest we have;

Volume = Mass / Concentration

Substituting the values we have;

Volume = 0.30 mg / 1 mg/mL = 0.3mL
