Answer:y/2
Explanation:
According to Avogadro's hypothesis which states that equal volume of gases at the same temperature and pressure contains the same number of molecules. Therefore volume is proportional to the number molecules. Since 100cm*3 of oxygen contains y molecules how many molecules will 50cm*3 of Nitrogen contains under the same temperature and pressure.
V=kn
V1/n1=V2/n2
Therefore nitrogen will contain y/2 molecules
