Empirical Formula Lab: Zinc Chloride


1. Find the mass of a clean, dry, labeled beaker. (49.45 g)

2. Add zinc to the beaker and find its mass. (52.72 g)

3. Add 50 ml of HCl to the beaker. Record observations.

4. Place the beaker on a hot plate to evaporate the water.

Day 2:

5. Find the mass of the zinc chloride left in the beaker.  Make sure all water has been driven off.

Final Mass of Beaker with Zinc Chloride:  56.27 g

Now, you have enough information to determine the empirical formula of Zinc Chloride.
