Your Answer
A
16 g O2 (g) and 4 g of H2 (g)
Your Answer
B
16 g of O2 (g) and 44 g of CO2 (g)
Correct Answer
C
28 g of N2 (g) and 32 g of O2 (g)
Correct Answer
D
12 g of C (s) and 23 g of Na (s)

Solution

The correct options are
C 28 g of N2 (g) and 32 g of O2 (g)
D 12 g of C (s) and 23 g of Na (s)
16 g O2=1632=0.5 mol=2×0.5×NA atoms=NA atoms
4 g H2=42=2 mol=2×2×NA atoms=4NA atoms
44 g CO2=4444=1 mol=3×1×NA atoms=3NA atoms
28 g N2=2828=1 mol=2×1×NA atoms=2NA atoms
32 g O2=3232=1 mol=1×2×NA atoms=2NA atoms
12 g C=1212=1 mol=NA atoms
23 g Na=2323=1 mol=NA atoms
