Answer
The ideal gas equation relating pressure (P), volume (V), and absolute temperature (T) is given as:
PV = nRT
Where,
R is the universal gas constant = 8.314 J mol–1 K–1
n = Number of moles = 1
T = Standard temperature = 273 K
P = Standard pressure = 1 atm = 1.013 × 105 Nm–2
∴ V = nRT / P
= 1 × 8.314 × 273 / (1.013 × 105)
= 0.0224 m3
= 22.4 litres
Hence, the molar volume of a gas at STP is 22.4 litres.

Answer:
since PV=nRT
V=nRt/P
puttin n=1 as we are considering 1 mole of gas, R=0.0821 and T=273 and P=1 atm
on solving you will get the required volume i.e. 22.4
