    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...
