The answer is 15mg

As we know that

The percentage can be written as

0.5 % solution means 0.5 / 100 = 0.005

Now 0.5 grams are equal to 500 milligrams.

So if we want to find percentage in 3mL we will write as

= 3 x (500 mg / 100 mL)

= 15 mg

The answer is: 15mg

0.5% means that there are 0.5 grams per 100 mL, and a 0.5 grams are equal to 500 milligrams.

So, to calculate how many milligrams will be received per injection, we need to make the following calculations:

3mL*(500mg)/(100mL)=15mg
