37.6 ml of H2 gas at 21.30 C collected in a buret by the electrolysis of an unknown metal and of sulfuric acid. A barometer measured atmospheric pressure at 0.987 atm. The solution level in the buret was 35.62 mm above the solution level in the beaker. At the end of the experiment the metal electrode lost 0.309 g. (a)Use Dalton’s law and determine the pressure of H2 gas in the buret.
