In a lab where molar volume of H2 gas is determined, it is important to allow the reaction to equilibrate for two minutes once it is complete. If you did not allow this to happen, what effect would it have on the calculated standard molar volume? Be specific—i.e. would you expect the calculated standard molar volume to be higher or lower than if you had waited?

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...

answer all parts: 2. You measured the volume of the CO2 by filling your flask with water and tightly inserting the stopper. a. Why was it necessary to tightly stop the water-filled flask and then remove the stopper before you emptied the water into a graduated cylinder for measurement? b. Would your calculated molar volume of CO2 (Vm) have been higher or lower if you had forgotten to stopper the flask before measuring the volume of the flask (V1)? Briefly...

Post Lab #1 A student was assigned the task of determining the molar mass of an unknown gas. The student measured the mass of a sealed 843 mL rigid flask that contained dry air. The student then flushed the flask with the unknown gas, resealed it, and measured the mass again. Both the air and the unknown gas were at 23.0°C and 750. torr. The data for the experiment are shown in the table below. Volume of sealed flask 843...
