Mole volume 1.2.3 - Coggle Diagram
Mole volume 1.2.3
STP ( Standard Temperature and Pressure)
T: 273k
P: 1atm
Definition of Molar Volume of gas:
The volume occupied by one mole of any gas is the same under the same conditions of temperature and pressure.
This volume is known as the molar volume (Vm)
At room temperature and pressure (rtp) the molar volume is 24 dm3.
Volume of gas to moles example:
1, 200cm^3 of CO2
N=V/Vm n=200/24000 n=0.00833=8.33x10^-3
Volumes of gas to mass of gas
Moles of gas to volumes of gas
Volume of gas = amount of gas x molar volume
v = n x Vm
Volume of gas to moles of gas
Amount of gas = volume of gas ÷ molar volume
n = v ÷ Vm
Volumes of gas to mass of gas
Molar volume = volume of gas ÷ amount of gas
Vm = v ÷ n
Moles of gas to volume of gas Example:
1, 1.00 mole of CO2
V=n x Vm. n= 1.00x 24000. n= 24000=2.40x10^4
