24: Kinetic Theory of Gases
- #1Calculate the volume of 1 mole of an ideal gas at STP.Ans : Here,
STP means a system having a temperature of 273 K and 1 atm pressure.
Pressure, P = 1.01325`` \times ``105 Pa
No of moles, n = 1 mol
Temperature, T = 273 K
Applying the equation of an ideal gas, we get
PV = nRT
⇒ V = `` \frac{RT}{P}``
⇒ V=`` \frac{8.314\times 273}{1.01325\times {10}^{5}}=0.0224{\,\mathrm{\,m\,}}^{3}``
