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.
