WebJul 1, 2024 · Avogadro's Law shows that volume or pressure is directly proportional to the number of moles of gas. Putting these together leaves us with the following equation: P1 … WebTo this point, four separate laws have been discussed that relate pressure, volume, temperature, and the number of moles of the gas: Boyle’s law: PV = constant at constant T and n. Amontons’s law: = constant at constant V and n. Charles’s law: = constant at constant P and n.
WebFor 2 moles of a gas at STP the volume will be 2 moles ⋅ 22.4 L/mol = 44.8 L For 0.5 moles the volume will be 0.5 moles ⋅ 22.4 L/mol = 11.2 L, and so on. The molar volume of a gas is derived from the ideal gas law P V = nRT: P V = nRT → V = nRT P → V n = RT P WebInitially the gas molecules move around to take up the entire volume of the container. Once you put all the gas molecules in one corner, you can see the total space in container …
WebAnswer: Find the molecular / atomic mass (if it is an inert gas). Take that numerical value in grams. So, for e.g., molecular mass of CO2 is 44u (12 + 2x 16). I drop the ‘u’ and put ‘g’ …
