1.40gO2 × 1molO2 /32.00gO2 = 0.0438mol O2 1.84gN2 × 1molN2 / 28.02gN2 = 0.0657molN2 The total number of moles of gas is 0.0438molO2 +0.0657molN2 = 0.1094mol At STP, 0.1094mol × 22.4L / 1mol = 2.45L I'm confused how 22.4L is there in the equation. Also why does oxygen O2 and nitrogen N2 have two atom. Is it because it's a gases so it's O2 and N2 instead of being O and N?

Question
1.40gO2 × 1molO2 /32.00gO2 = 0.0438mol O2
1.84gN2 × 1molN2 / 28.02gN2 = 0.0657molN2
The total number of moles of gas is
0.0438molO2 +0.0657molN2 = 0.1094mol
At STP,
0.1094mol × 22.4L / 1mol = 2.45L
I'm confused how 22.4L is there in the equation. Also why does oxygen O2 and nitrogen N2 have two atom. Is it because it's a gases so it's O2 and N2 instead of being O and N?
