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

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 of particles.

According to ideal gas equation:

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

V = Volume of gas = ?

n = number of moles = 1

R = gas constant =

T =temperature =  (at STP)

Thus 1 mole of every gas occupies 22.4 L at STP

the answer is 75.0%.
