molar volume

Molar volume is the volume occupied by one mole of a substance at a specific temperature and pressure. For gases, it indicates how much space a certain amount of gas takes up under standard conditions, helping us understand and compare the densities and behaviors of different gases. For solids and liquids, molar volume relates to how tightly packed the molecules are. It’s a useful concept in chemistry for calculating quantities and understanding the relationships between different substances, providing a consistent way to relate amount of substance to its physical space.
