Answer 1

78 mg/hr

Explanation:

Given,

• Total amount of solution = 32 mL

• Amount of dopamine in solution = 208 mg

• Rate of flow of solution = 12 ml/hr

Since, 32 mL contains dopamine = 208 mg

`=>\textrm{ 1 mL of solution contains dopamine}=\ (208)/(32)`

`=>\textrm{ 12 mL of solution contains dopamine}=\ (208)/(32)* 12`

= 78 mg

Since, 12 mL of solution contains 78 mg of dopamine and rate of flow of solution is also 12 mg/hr and since dopamine is also flowing with solution. So, the rate of flow of dopamine is 78 mg/hr.
