Answer:

Step-by-step explanation:

To calculate the empirical formula of a metal bromide given the mass of cobalt and the mass of the metal bromide formed, you need to follow these steps:

Step 1: Find the Mass of Bromine

Subtract the mass of cobalt from the mass of the metal bromide to find the mass of bromine.

Step 2: Calculate Moles

Use the molar mass of cobalt and bromine to calculate the moles of each element.

Step 3: Find the Ratio

Divide the moles of each element by the smallest number of moles calculated. This will give you the mole ratio.

Step 4: Write the Empirical Formula

Write the empirical formula using the whole number mole ratios. If necessary, multiply the ratios by a common factor to obtain whole numbers.
