What is molar volume used for?
For an ideal gas, 22.4 Lmol–1. (2) The molar volume, symbol Vm is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ).
How is the volume of a gas determined?
The volume of a gas is determined by the volume of the container it is in. Gases take the shape of their container and the volume of the container….
What is the molar volume of gas at STP?
22.4L
The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole (6.02×1023 representative particles) of any gas occupies a volume of 22.4L (figure below). Figure 10.13. 2: A mole of any gas occupies 22.4L at standard temperature and pressure (0oC and 1atm).
What is meant by molar volume of a gas *?
The volume occupied by one mole of a gas at standard temperature (0°C) and pressure (1 atm) (STP) is called a molar volume of a gas. The molar volume of a gas at STP is 22.4 dm3.
When determining the moles of a gas from the volume of that gas Why is it important that the volume be measured at STP?
It is important to measure the volume of a gas at STP in order to calculate the number of moles of that gas present in the sample volume. This is because STP conditions allow a standard for comparison. At STP, which is 0°C and 1 atm pressure, 1 mol of any gas occupies a volume of 22.4 L.
What is meant by the molar volume of a gas?
The molar volume is the volume occupied by one mole of any gas, at room temperature and pressure. The molar volume is equal to 24 dm 3 (24,000 cm 3). This volume is given in questions that need it.
What is molar volume at RTP?
One mole of any gas has a volume of 24 dm 3 or 24,000 cm 3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas.
