What does Avogadro's law say about a gas atSTP? A; 1 L of any gas contains 22.4 moles at STP B; 1 L of any gas has a pressure of 22.4 atm at STP C; All gases are at 22.4 atm at STP D; 1 mole of any gas has a volume of 22.4 L at STP

Respuesta :

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

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

According to ideal gas equation:

[tex]PV=nRT[/tex]

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

V = Volume of gas = ?

n = number of moles = 1

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]273K[/tex]  (at STP)

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{1mol\times 0.0820 L atm/K mol\times 273K}{1atm}=22.4L[/tex]

Thus 1 mole of every gas occupies 22.4 L at STP
