Answer: [tex]30.64\times 10^{23}molecules[/tex]
Explanation: According to Avogadro's law, 1 mole of every substance occupies 22.4 Liters at standard temperature and pressure and contains avogadro's number [tex](6.023\times 10^{23})[/tex] of particles.
22.4 L of oxygen gas[tex](O_2)[/tex] contains =[tex]6.023\times 10^{23}[/tex] molecules of oxygen
113.97 L of oxygen gas[tex](O_2)[/tex] contains =[tex]\frac{6.023\times 10^{23}}{22.4L}\times 113.97L=30.64\times 10^{23}[/tex]molecules of oxygen
