This mass represents approx. #2*mol# with respect to #"dinitrogen"#..........

Explanation:

As always #"Number of moles"# #=# #"Mass"/"Molar mass"#.

And #N_2# has a molar mass of #28.02*g*mol^-1#. From where did I get this figure? From where will you get it, if you are asked this question in an exam?

And so we solve the quotient, #(52*g)/(28.0*g*mol^-1)=??*mol#. Why do I get an answer with units of #mol#?
