$The volume of 1 mole of any pure gas at standard temperature and pressure is always equal to$

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

A $0.022414 m^{3}$
B $2.2414 m^{3}$
C $22.414 m^{3}$
D $0.22414 m^{3}$

Correct answer: A

Solution

(a) The volume of 1 mole of any pure gas at standard and pressure (STP) is equal to 22.414 L 1 L = 10^{- 3} m^{3} ∴ 22.4 L = 0.022414 m^{3}
