Please help I’m stuck!!
If a drug has a concentration of 115 mg per 5 mL, how many milliliters are needed to deliver 3 grams of the drug? Express your answer rounded to the nearest milliliter.
a drug has a ratio of 115mg:5ml. This is equivalent to 23mg:1ml. 3g=3000mg, so we divide 3000 by 23 to get 130.434783. That is how many milliliters are needed. We round it to get 130 mL.
