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 drug - concentration per mL

The concentration of the drug in the solution is found 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 $c$ (in mg/mL) is $c=\frac{12}{5}$ mg/mL.

Step2: Calculate drug amount in 24 mL

To find the amount of drug $m$ in 24 mL of the solution, we use the formula $m = c\times V$, where $V = 24$ mL. Substituting $c=\frac{12}{5}$ mg/mL and $V = 24$ mL, we get $m=\frac{12}{5}\times24$.
$m=\frac{12\times24}{5}=\frac{288}{5}=57.6$ mg.

Answer:

57.6 mg
