Drug A has a concentration of 475 mg/10 mL. How many grams are in 100 mL of Drug A? (Round to the nearest tenth if applicable).

Answer: There are 4.8 grams in 100 mL of Drug A

Step-by-step explanation:

In order to determinate how many grams are in 100 mL of Drug A you can multiply and divide the expression of the concentration by 10 (To obtain 100 mL in the denominator)

Notice that the value remains unaltered.

(475 mg/10 mL) (10/10) = 4750 mg / 100 mL

But the question is how many grams are in 100 mL, so you have to convert the value from mg to g.

The prefix m (mili) is equivalent to 0,001 so you can use 0.001 instead of the prefix

4750 (0.001) g / 100 mL

4.75 g / 100 mL

The rounded result is 4.8 g / 100 mL
