Question

q2. every 5 ml of a solution contains 12 mg drug. how many milligrams of drug are in 24 ml solution?

Explanation:

Step1: Find the drug - concentration per ml

The concentration is calculated by dividing the amount of drug by the volume of the solution. Given that 5 mL of the solution contains 12 mg of drug, the concentration $c$ is $c=\frac{12}{5}$ mg/mL.
$c = \frac{12}{5}=2.4$ mg/mL

Step2: Calculate the amount of drug in 24 mL

To find the amount of drug $m$ in 24 mL of the solution, we multiply the concentration $c$ by the volume $V$.
$m=c\times V$
Substitute $c = 2.4$ mg/mL and $V = 24$ mL into the formula.
$m=2.4\times24 = 57.6$ mg

Answer:

57.6 mg
