Correct Answer is ["6.7"]
Explanation
Given:
Desired dose of ferrous sulfate: 120 mg
Concentration of ferrous sulfate syrup: 90 mg/5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
120 mg / Volume = 90 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 120 mg / (90 mg/5 mL)
Step 4: Calculate the volume:
Volume = 120 mg / 18 mg/mL
Volume = 6.666666667 mL
Step 5: Round to the nearest tenth:
Volume ≈ 6.7 mL
