Calculate the volume of 1 mole of an ideal gas at STP.
STP means standard temperature-273.15K and pressure 101.325 kPa.
Given
Pressure P=1.01Pa
Number of moles n=1
Temperature T=273.15K
We know ideal gas equation
PV=nRT
Where V= volume of gas
R=gas constant =8.3JK-1mol-1
T=temperature
n=number of moles of gas
P=pressure of gas.
So, we can write
The volume of 1 mole of an ideal gas at STP=0.0224m3.
