chemisttree said:When you are describing "MOLAR VOLUME" the 'per mole' is understood and thus the units are cm^3 (cm^3/mol if you want to be pedantic).
Molar volume is the volume of one mole of a substance at a specific temperature and pressure. It is an important concept in chemistry because it allows us to compare the volumes of different substances and calculate their properties, such as density and molar mass.
Molar volume is typically measured using the ideal gas law, which relates the volume, pressure, temperature, and amount of a gas. By manipulating the equation, we can solve for the molar volume of a gas sample.
Molar volume is typically expressed in liters per mole (L/mol) or cubic meters per mole (m3/mol). However, other units such as milliliters per mole (mL/mol) may also be used.
To convert between molar volume and other units of volume, you can use conversion factors based on the relationship between the units. For example, 1 L/mol is equal to 1000 mL/mol and 1 m3/mol is equal to 1,000,000 mL/mol.
According to the ideal gas law, molar volume increases as temperature and pressure increase. This is because an increase in temperature causes gas molecules to move faster and take up more space, while an increase in pressure compresses the gas and reduces its volume. However, this relationship is only true for ideal gases under ideal conditions.
