For this problem, we have to determine the empirical formula of the given ionic compound MCl_{x}

We will be following these steps:

**Step 1.** Find the moles of metal cation

**Step 2.** Find the moles of electron reacted

**Step 3.** Find the ratio of mol electron over mole of Metal cation

**Step 4. **Write the empirical formula

The molar mass of a unknown metal (M) is 50.9 g/mol and it forms a chloride of unknown composition (MCl_{x}). Electrolysis of a sample of this molten chloride with a current of 6.42 amps for 23.6 minutes produces 1.20 grams of the metal M at the cathode. Solve for the empirical formula of the chloride (i.e. solve for x in MCl_{x}). Show all work and circle your final answer.
