Under same conditions of temperature and pressure if you collect 3 litre of O_(2), 5 litre of Cl_(2) and 6 litre of H_(2), i. Which has the highest number of molecules? ii. Which has the lowest number of number of molecules?

Under same conditions of temperature and pressure if you collect 3 lit

1.	Under same conditions of temperature and pressure if you collect 3 litre of O_(2), 5 litre of Cl_(2) and 6 litre of H_(2), i. Which has the highest number of molecules? ii. Which has the lowest number of number of molecules?
Answer» SOLUTION :`"Number of moles of "O_(2)=("Volume of S.T.P")/("Molar volume")` `=(3)/(22.4)="0.1339 moles"` `"Number of MOLECULES"="Number of moles"xx"Avogadro number"` `=0.1339xx6.023xx10^(23)` `=0.8064xx10^(23)` `=8.064xx10^(22)O_(2)` molecules. `"Number of moles of "Cl_(2)=(5)/(22.4)="0.2232 moles"` `"Number of molecules"=0.2232xx6.023xx10^(23)` `=1.344xx10^(23)" molecules."` `"Number of moles of "H_(2)=(6)/(22.4)=0.2678" moles"` `"Number of molecules"=0.2678xx6.023xx10^(23)` `=1.6129xx10^(23)" molecules."` i. 6 litre of `H_(2)` has the highest number of molcules. ii. 3 litres of `O_(2)` has the LOWEST number of molecules.
