Answer 2

Answer: 1 mole of any gas has a volume of 22.4 L at STP

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
`6.023* 10^(23)` of particles.

According to ideal gas equation:

`PV=nRT`

P = pressure of gas = 1 atm (at STP)

V = Volume of gas = ?

n = number of moles = 1

R = gas constant =
`0.0821Latm/Kmol`

T =temperature =
`273K` (at STP)

`V=(nRT)/(P)`

`V=(1mol* 0.0820 L atm/K mol* 273K)/(1atm)=22.4L`

Thus 1 mole of every gas occupies 22.4 L at STP
