WebAvogadro’s Law: The Volume Amount Law. Avogadro’s law states that for constant temperature, pressure, and volume, all the gases contain an equal number of molecules. 1 mole of any gas at NTP occupies a volume of 22.4L. It is important for determining the relationship between the amount of gas (N) and the volume of the gas (V). WebAt 15 degress celsius, you need more moles (56.3 moles instead of the 54.4 moles) to reach 23.8 mm Hg because the molecules have lower kinetic energy. That does not mean, that at 15 degrees, the equilibrium point (vapor pressure) is still 23.8 mm Hg. At 15 degress the vapor pressure of water is 12.8 mm Hg. So that does agree with your intuition. matt spanish moss paintWebThis law says that for an ideal gas, the gas’s pressure times its volume is equal to the number of moles of the gas multiplied by a constant times the gas’s temperature.
