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?

Pre-lab for Molar Volume of a Gas How much volume does a gas occupy under standard conditions of temperature (O°C or 273 K) and pressure (1 atm or 760 mmHg)? As you knew from high school, after reading the lab manual, or from lecture, you already know the answer is 22.4 L per mole (L/mol). Thus, this is more of a verification than a true experiment. In a nutshell, you will generate hydrogen gas via a reaction, collect that gas...

A sample of hydrogen is collected over water at a temperature of 230C. The pressure inside the tube is determined to be 689 mmHg, and 12.10 mL of gas has been collected. What would the volume of collected hydrogen be at STP? a weird lab decided to use glycerin, a liquid with a density of 1.260 g/mL. If the water level inside the tube was 12.31 cm higher than outside the tube, and the atmospheric pressure measured 728 mmHg, what...
