Molar volume is the volume occupied by one mole of a substance at a given temperature and pressure, typically measured in liters per mole (L/mol). It is a fundamental concept in gas laws, as it helps relate the amount of gas to its volume under specific conditions. For ideal gases at standard temperature and pressure (STP), the molar volume is approximately 22.4 L/mol, which highlights the relationship between gas volume and the number of moles present.
congrats on reading the definition of molar volume. now let's actually learn it.
