In chemistry and related fields, the molar volume, symbol V m, [1] or ~ of a substance is the ratio of the volume (V) occupied by a substance to the amount of substance (n), usually at a given temperature and pressure.
The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions. The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal ...
Convert liters to moles and moles to liters using our conversion calculator, plus learn the volume to quantity of substance formula.
Conversions Between Moles and Gas Volume. Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of 1mol = 22.4L 1 mol = 22.4 L is the basis for the conversion factor. Example 10.7.1 10.7. 1: Converting Gas Volume to Moles.
25 maj 2014 · The Molar Volume of an ideal gas at STP, which we define to be 0∘C and 1 atm arbitrarily (because we're old-fashioned and stuck in 1982) is 22.411 L/mol. To calculate this we can use the Ideal gas law of P V = nRT.
28 maj 2024 · The resultant equality, 1 mol Cl 2 = 22.4 L Cl 2, must then be applied as a conversion factor to eliminate the given unit, "liters of molecular chlorine." Applying the correct number of significant figures to the calculated quantity results in the final answer that is shown below.
One of the most practical results of this law is the molar volume of a gas, Vm, which is about: Vm = 22.4 dm3 / mol. It means, at standard temperature (273.15 K, 0°C) and standard atmospheric pressure (101.325 kPa), the molar volume is the same for all ideal gases. Note that it is under the ideal gas assumption.
