We are asked which of the following compounds hasthe highest mass percent of O a. Mn2O3b. MnO c. Mn3O2d. MnO2

To do that we’re going to use themass percent formulashown below:

mass% O = mass of Omass of MnxOy x 100%

First, we need to get theatomic weights of each element Mn and Ousing theperiodic tableand then calculate its molar mass. Then compute for the mass % of O.
