There are 80 mg/0.8 mL in Acetaminophen Concentrated Infant Drops. If the proper dosage for a four-year-old is 240 mg, how many milliliters should the child receive?

1. 0.8 mL

2. 1.6 mL

3. 2.4 mL

4. 3.2 mL

The correct answer is: 2.4 mL

To determine how many milliliters of the Acetaminophen Concentrated Infant Drops a four-year-old should receive for a proper dosage of 240 mg, we first need to understand the concentration of the drops. The solution indicates that there are 80 mg of Acetaminophen in 0.8 mL. To find out how many milliliters would provide a dosage of 240 mg, we can set up a proportion based on the concentration already given: 1. Start with the concentration: 80 mg corresponds to 0.8 mL. 2. We need to find out how many milliliters (let's call this \( x \)) will yield 240 mg. Setting up the proportion, we have: \[ \frac{80 \text{ mg}}{0.8 \text{ mL}} = \frac{240 \text{ mg}}{x \text{ mL}} \] Now, cross-multiplying to solve for \( x \): \[ 80 \text{ mg} \cdot x \text{ mL} = 240 \text{ mg} \cdot 0.8 \text{ mL} \] Calculating the right
