Expert Answer:

Gram space atoms space is space the space mass space of space straight a space substance space that space contains space 1 space mole space of space atoms
Here comma
2 space gm space atoms space of space nitrogen space equals space 2 space mole space of space nitrogen left parenthesis straight N right parenthesis

therefore space mass space of space 2 space gm space of space straight N subscript 2 space equals space 2 cross times 14 over 1

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 28 space straight g

1 space mole space of space silver space equals space molar space mass space of space silver
space space space space space space space space space space space space space space space space space space space space space space
space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 108 space gm
space space
22.4 space lit space of space oxygen space at space STP
22.4 space litre space of space oxygen space equals space 1 space mole space of space oxygen
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 16 space gm
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 16 cross times 2
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 32 space gm space of space straight O subscript 2
6.022 cross times 10 to the power of 23 space atoms space of space carbon

6.022 cross times 10 to the power of 23 space atoms space of space straight C space equals space 1 space mole space of space carbon
space space space space space space space space space space space space 1 space mole space of space Carbon space equals space 12 space gm

So comma space 6.022 cross times 10 to the power of 23 space atoms space of space carbon space will space weigh space least.
The space order space will space be
Ag greater than straight O subscript 2 greater than straight N subscript 2 space greater than straight C
