Explanation:

Problem 1

Step1: Determine the dosage formula

The formula for calculating the volume to administer is $\text{Volume} = \frac{\text{Desired Dose}}{\text{Dose per Volume}}$. First, find the dose per ml. The supply is 80 mg in 2 ml, so the concentration is $\frac{80\space mg}{2\space ml} = 40\space mg/ml$.

Step2: Calculate the volume

We need to give 60 mg. Using the formula, $\text{Volume} = \frac{60\space mg}{40\space mg/ml} = 1.5\space ml$.

Step1: Find the concentration

The supply is 250 mg in 5 ml, so the concentration is $\frac{250\space mg}{5\space ml} = 50\space mg/ml$.

Step2: Calculate the volume

We need to give 500 mg. Using the formula $\text{Volume} = \frac{\text{Desired Dose}}{\text{Concentration}}$, we get $\text{Volume} = \frac{500\space mg}{50\space mg/ml} = 10\space ml$.

Step1: Use the caplet formula

The formula for the number of caplets is $\text{Number of Caplets} = \frac{\text{Desired Dose}}{\text{Dose per Caplet}}$.

Step2: Calculate the number of caplets

The desired dose is 500 mg and each caplet is 250 mg. So, $\text{Number of Caplets} = \frac{500\space mg}{250\space mg/caplet} = 2\space caplets$.

Answer:

1.5 ml
