6.022×10^23 molecules of co2 are present in its molar volume. Molar volume is basically the volume of one mole of specific substance. We know that, one mole of substance contains Avogadro's number (6.022×10^23) particles.

At standard conditions, 1 liter of air at 21% oxygen possesses 0.21 L of oxygen. Since at STP 1 mole of gas occupies 22.4 L, simply divide 0.21/22.4, to arrive at 0.0094 moles of oxygen.

Explanation: Recall that moles can be converted to particles using Avogadro's constant ( 6.022⋅1023 ) which is the number of molecules per mole of a substance. In 1.5 moles of fluorine gas, there are 1.5⋅6.022⋅1023 molecules of gas.
