In 100 gm of air it contains 25 gm of CO2, 25 gm of O2 and 50 gm of N2.
Now for CO2; (44*25)/100 = 11 gm,
for O2; (32*25)/100 = 8 gm,
for N2; (28*50)/100 = 14 gm,
So, the average molecular weight is 11+8+14 = 33gm.
Now for CO2; (44*25)/100 = 11 gm,
for O2; (32*25)/100 = 8 gm,
for N2; (28*50)/100 = 14 gm,
So, the average molecular weight is 11+8+14 = 33gm.
