Question

Q. A pharmacist mixes 3 grams of compound with 5,000 milligrams of solution to create a prescription. How many total grams is the prescription?

Answer 1

Answer: 8 grams

Step-by-step explanation:

We have two units of mass: grams and milligrams

The prescription has 3 grams of compound with 5,000 milligrams of solution.

To know how many grams in total there are in the mixture we must convert

5000 milligrams to grams.

By definition in 1 gram there are 1000 mg.

Then we perform the following operation

$5000\ mg * \frac{1\ grams}{1000\ mg}=5\ grams$

Then the total amount of grams in the prescription is:

$5+ 3=8\ grams$
