In the electrolysis experiment similar to the one employed in this experiment; a student observed that his unknown metal anode lost 0.238 grams while a total volume of 94.50 mL of hydrogen was being produced. The temperature of the solution was 25 °C and the barometric pressure was 740 mm Hg. The vapor pressure of water at 25 °C is 23.8 mm Hg. 1. What is the pressure of the hydrogen gas in atmospheres? 2. What is the volume...

3. Nitrogen gas was collected in a eudiometer during a chemistry experiment by displacement of water. When the levels of water inside and outside the eudiometer were adjusted to be the same, the volume of the collected gas was found to be 85.2 mL. The water temperature was 24°C and the barometric (atmospheric) pressure was found to be 764.0 mm Hg. What would be the volume of dry nitrogen gas at STP?
