4. Dilute hydrochloric acid is added to a 0.500 g sample of an alloy containing zinc and copper. The gas evolved is collected over water using an apparatus like the one you used in Experiment 14. The following data were obtained: 737 mm Hg barometric pressure (corrected) 23 C temperature of gas 109 mm difference in water levels inside and outside tube 79.7 mL volume of gas collected Calculate the percentage of zinc in the alloy.
