Question

Calculate the volume of 1 mole of an ideal gas at STP.

Answer 1

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=$\frac{8.314\times 273}{1.01325\times {10}^5}=0.0224{\mathrm{m}}^3$
