The Ideal gas law shows the relationship between some common properties of ideal gases and is written as PV = nRT. P = pressure, V = volume, n = number of moles of ideal Gas, R = General gas constant = 8.314 kJ/(kmol.K) and T = absolute temperature. 5 mol ideal gas at 22°C is placed in a cube with edge lengths of 0.750 meters. Calculate the pressure of the Ideal gas as [Pa].
The equation of state of an ideal gas describes the relationship between its pressure p, volume V,
and temperature T as:
PV = nRT
where n is the amount of substance of gas (number of moles), and R is the ideal gas constant.
What are the dimensions of R?
