Exercise 238

A health care professional has just finished preparing 250 mL of a 6% solution (using a dry drug) when he learns that the physician wants an 8% solution, not a 6% solution. How many additional grams of dry drug should the health care professional add to the 6% solution he has just prepared? (Assume that adding the dry drug does not affect the total volume of solution.)
