Question
Calculate the volume of 1 mole of an ideal gas at STP.
Advertisements
Solution
Here,
STP means a system having a temperature of 273 K and 1 atm pressure.
Pressure, P = 1.01325\[\times\]05 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=\[\frac{8 . 314 \times 273}{1 . 01325 \times {10}^5} = 0 . 0224 \text{ m}^3\]
