To find the empirical formula of the cobalt oxide, we will follow these steps: ### Step 1: Calculate the mass of oxygen in the sample We know the total mass of the oxide and the mass of cobalt. We can find the mass of oxygen by subtracting the mass of cobalt from the total mass of the oxide. \[ \text{Mass of Oxygen} = \text{Total Mass of Oxide} - \text{Mass of Cobalt} \] ...
