I am stuck on these 2 problems, and the formulas that I am using I don't believe are working to find the correct answer.
You have 4 oz of a 50% solution. If 500 mL was added to the 50% solution what is the percentage strength of the new solution?
If 14 grams of petrolatum is added to 25 grams of 0.2% hydrocortisone ointment, what will be the final percent concentration of the hydrocortisone?
