Identify the true statements describing the experimental set-up in the Measuring Avogadro's Number experiment. Select one or more: The plastic spacer should be placed between the two strips of metal. Each set-up should have one strip of copper and one strip of zinc. The metal strip with the red lead is the one that should have its mass measured. Only deionized water should be present in the liquid around the metal strips.
