For a medication with a standard dose of 75 mg per individual, how many individuals can be treated with a 3g vial of that medication?

To determine how many individuals can be treated with a 3g vial of medication when the standard dose is 75 mg, it’s important to first convert the vial's dose into milligrams. A vial containing 3 grams can be converted to milligrams since 1 gram equals 1,000 milligrams. Therefore, a 3g vial is equal to 3,000 mg (3g x 1,000 mg/g = 3,000 mg).

Next, to find out how many individuals can be treated, divide the total amount of medication in milligrams by the standard dose per individual:

3,000 mg ÷ 75 mg/individual = 40 individuals.

This means a 3g vial can treat 40 individuals, confirming option B as the correct answer based on the calculation. It's important to carefully perform each step, ensuring accurate conversions and divisions. Understanding the process ensures that the technician can confidently perform similar calculations in real-world scenarios.
