Question

You have collected (a) 2 litres of CO2 (b) 3 litres of chlorine (c) 5 litres of Hydrogen (e) 4 litres of nitrogen and (e) 1 litre of SO2, under similar conditions of temperature and pressure. Which gas sample will have : The greatest no. Of molecules n (b) least no. Of molecules

Answer 1

a.1 lit of CO2 will contain 6×10^23 molecules
2 lit will contain 12× 10^23 molecules
b.3lit of Cl2 will contain 18×10^23 molecules
c.5l of hydrogen will contain 30×10^23 molecules
d 4l of nitrogen will contain 24 ×10^23 molecules
e.1l of SO2 will contain 6×10^23 molecules

therefore
i)5l of Hydrogen contains maximum number of molecules
ii)1l of SO2 will contain least number of molecules

Answer 2

Answer: Greatest is H2 and the least is SO2
