QUESTION 4
A student collected a sample of hydrogen gas in a eudiometer over a water bath to experimentally determine the value of the gas constant, R.
Calculate the experimental value of R if the pressure of the gas was 0.991 atm, the volume was 36.3 mL, the temperature was 292 K, and the sample contained 1.54 x 10-3 moles of gas

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?
