#"A 16 g mass..."#

Explanation:

Most of the elemental gases, certainly the gases with any chemistry are BINUCLEAR... We speak of #"dinitrogen"#, #"dioxygen"#, #"dihalogen"#...

And so given a #16*g# mass of #O_2#...we gots HALF a mole of #O_2# #"oxygen molecules"#, and this is EQUIVALENT to #"ONE MOLE"# of #"oxygen atoms"#...
