Thank you! GravimetryZinc Oxide and Salicylic Acid Paste, USPZnO                         81.3 g/moleC7H6O3                 138.1 g/mole Zinc Oxide and Salicylic Acid Paste contains not less than 23.5 percent and not more than 25.5 percent of zincoxide (ZnO), and not less than 1.9 percent and not more than 2.1 percent of salicylic acid (C7H6O3). ANSWER THE FOLLOWING: A. Assay Procedure Arrange the steps in the assay of zinc oxide content. Write only the letter that corresponds to the first step, second step, and so on. For example:1. b2. c…. Choices:   a. Ignite the mass strongly until all the carbonaceous matter has dissipated.   b. Weigh 500 mg of the paste in a tared porcelain crucible.   c. Weigh the cooled yellow residue.   d. Continue heating until the mass is thoroughly charred.  e. Heat gently until the sample is completely melted. B.
