At what temperature (in °C) does 12.41 g of neon occupy a volume of 12.78 L at a pressure of 1.03 atm? Report your answer to 3 significant figures and do not include units in your answer. ОС -13.5 Use the ideal gas law to help you after first converting to moles. Note the answer asks for temperature in celsius and that the temperature must be in kelvin when using the Ideal Gas Law.

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...
