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?
A volume of 30.0 mL of nitrogen gas was collected over water at 24.0°C and 0.98 atm. The vapor pressure of water at this temperature is 0.03 atm. a. What is the partial pressure of the nitrogen gas sample, (use Dalton's law)? b. What would the new volume of this gas be at STP. (Use the combined gas law)?
