Calculations involving specific gravity
A prescription is written for 60 g of zinc oxide ointment, USP. If the formula for zinc oxide ointment, USP is as follows: 200 g of zinc oxide powder, 650 g of white ointment, and 150 gram of mineral oil to make 1000 grams of zinc oxide ointment, USP; how much of each ingredient will you need to fill this order? Using the information from the previous page (mineral oil has a specific gravity of 0.845 to 0.905) determine your quantity of mineral oil required for this prescription in milliliters.
