The number of oxygen molecules exists present in 113.97 liters of oxygen gas at STP is [tex]$ 30.64 * 10^{23}[/tex].
What is Avogadro's law?
Avogadro's law exists as an experimental gas law describing the volume of a gas to the quantity of substance of gas present.
According to Avogadro's law, 1 mole of every substance occupies 22.4 Liters at standard temperature and pressure and contains Avogadro's number of particles.
22.4 L of oxygen gas ([tex]O_{2}[/tex]) contains = [tex]$6.02*10^{23}[/tex] molecules of oxygen
113.97 L of oxygen gas ([tex]O_{2}[/tex]) contains = [tex]$(6.02*10^{23} /22.4 L)*113.97L[/tex]
[tex]$= 30.64 * 10^{23}[/tex] molecules of oxygen
Therefore, the correct answer is option D.[tex]$ 30.64 * 10^{23}[/tex].
