One mole of any gas at STP takes up 22.4 L of volume.
one mole of gas = 22.4 L ..... (a)
one mole of gas has 6.02 x
10
23
particles( Molecules) ..... (b)
equating (a) and (b) we get
6.022 x
10
23
particles (Molecules) = 22.4 L
Making conversion factors 22.4 L / 6.02 x
10
23
particles or
6.02 x
10
23
particles / 22.4 L
since we want change the # of molecules into L we will use the conversion factor that when multiplied by the given number
gives L as the final unit.
3.01 x
10
23
particles x 22.4 L / 6.02 x
10
23
particles
11.2 L
