Calculate the number of molecules and number of atoms present in 11.2

1.	Calculate the number of molecules and number of atoms present in 11.2 litres of oxygen (O_(2)) at N.T.P
Answer» Solution :22.4 LITRES of `O_(2)` at N.T.P contain `= 6.022xx10^(23)` molecules 11.2 litres of `O_(2)` at N.T.P contain `= (11.2)/(22.4)xx6.022 XX 10^(23)` molecules `= 3.01 xx 10^(23)` molecules `= 6.02 xx 10^(23)` ATOMS.
