The equation of state of an ideal gas which is a good approximation to real gases at sufficiently high temperatures and low pressures; that is, PV = RT, where P is the pressure, V is the volume per mole of gas, T is the temperature, and R is the gas constant. The Ideal Gas Law (General Gas Equation) is the equation of state of a hypothetical ideal gas.
Gas Equation: PV = nRT
Where,
P = pressure,
V = volume,
n = moles of gas,
T = temperature,
R = 8.314 J K^{-1} mol^{-1}, ideal gas constant.
Example:
Calculate the Volume of gas through Ideal Gas Law equation.
Temperature = 20 K
Pressure = 30 kPa
Moles of Gas = 2.50 moles
Solution:
Apply Formula:
Gas Equation: PV = nRT
Volume = 55.43 L
