Answer:

There are 4,000 milligrams

Step-by-step explanation:

We know that in 1 gram there are 1000 milligrams

To calculate how many milligrams equals 20 grams we perform the following operation

[tex]20\ g*\frac{1000\ mg}{1\ g}=20,000\ mg[/tex]

Then 100 mL of a solution contains 20,000 mg

To calculate how many milligrams there are in 20mL of the solution we perform the following operation

[tex]20\ mL*\frac{20,000\ mg}{100\ mL}=4,000\ mg[/tex]
