You may need to open the injector cap just prior to each trial but keep the initial volume the same at each trial.Explanation / Answer
Q1.
volume of air=30 cm^3=30 ltr
volume of N2=0.7*30=21 ltr
as we know, 22.4 ltr contains 1 mole of the gas.
then number of N2 molecules=(21/22.4) moles=0.9375 moles
=0.9375*6.023*10^23=5.6466*10^23
volume of O2=0.2*30=6 ltr
number of O2 molecules=(6/22.4) moles=0.26786 moles
=0.26786*6.023*10^23
=1.6133*10^23
