Calculate the number of molecules in each of the following : 1 g N_2 , 1 g CO_2 . ( Given that N_a is 6.02 xx 10^23 , molecular mass of N_2 is 28 and CO_2 is 44).

A given compound always contatins exactly the same proportion of elements by weight’. Calculate the number of molecules in each of the following: 1g N_2 (Given that N_A is 6.02xx10^23 , molecular mass of N_2 is 28 and CO_2 is 44).

For one-electron species, the wave number of radiation emitted during the transition of electron from a higher energy state (n_(2)) to a lower energy state (n_(1)) is given by: bar v =(1)/(lamda)=R_(H) xx Z^() ((1)/(n_(1)^(2)) (1)/(n_(2)^(2))) where R_(H)=(2 pi m_(s) k^(2) c^(4))/(h^(3) c) is Rydberg constant for hydrogen atom. Now, considering nuclear motion, the accurate measurement would be obtained by replacing mass of electron (m_(e)) by the reduced mass (mu) in the above expression, defined as mu =(m_(n)xx m_(e))/(m_(n) +m_(e)) where m_(n) = mass of nucleus. For Lyman series, n_(t) =1 (fixed for all the lines) while n_(2) = 2, 3, 4 .... For Balmer series: n_(1) = 2 (fixed for all the lines) while n_(2) = 3,4,5 .... The ratio of the wave numbers for the highest energy transition of electron in Lyman and Balmer series of hydrogen atom is
