Question

Dalton’s Law:Dilute hydrochloric ácidos added to a 0.500 g sample of an alloy containing zinc and copper.The has evolved is collected over water using an apparatus and the following data were obtained:

  1. Barometric pressure(corrected) 737.1 mm Hg
  2. Temperature of the gas 25 degrees C
  3. Aqueous vapor pressure @ 25 degrees C 23.8 mm Hg
  4. Difference in water levels inside and outside tube 109 mm H2O
  5. The mm H2O per 1 mm Hg 13.6 mm H2O
  6. Volume of gas collected 81.3mL

Calculate the percentage of zinc in the alloy
