Dinitrogen tetroxide decomposes to give nitrogen dioxide according to equation below
N2O4--->2NO2
According to avogadros law
1 moles =22.4 l
what about 2.45 l
=2.45l x1 mole/22.4=0.1094 moles
by use of reacting ratio that 1 :2
the moles of No2 = 0.1094 x2=0.2188 moles
1 moles= 22.4 l
what about 0.2188moles
=(0.2188moles x22.4 l) /1moles=4.90 L
