List - I Mass of substance		List - II Number of atoms
A.	1.8 mg water	I.	\( 2 \times 10^{-4} \times \mathrm{N}_{\mathrm{A}} \)
B.	9.8 mg sulphuric acid	II.	\( 1.5 \times 10^{-4} \times \mathrm{N}_{\mathrm{A}} \)
C.	1.8 mg carbon	III.	\( 3 \times 10^{-4} \times \mathrm{N}_{\mathrm{A}} \)
D.	5.85 mg salt $(\mathrm{NaCl})$	IV.	\( 7 \times 10^{-4} \times \mathrm{N}_{\mathrm{A}} \)
