Which of the following contains maximum number of atoms?

Options

A. 2.0 mol of `S _(8)`
B. 6.0 mol of S
C. 5.5 mol of `SO_(2)`
D. `44.8` L of `CO _(2)` at S.T.P

Answer

C

Explanation

(a) Atoms in 2. 0 mol of `S _(8)`
`= 2 xx 8 xx 6. 02 xx 10 ^(23) = 9. 632 xx 10 ^(24)`
(b) Atoms in 6.0 mol of S
`= 6 xx 6.02 xx 10 ^(23) = 3. 612 xx 10 ^(24)`
(c) Atoms in 5.5 mol of `SO _(2)`
`= 3 xx 5.5 xx 6. 02 xx 10 ^(23) = 9.93 xx 10 ^(24)`
(d) Atoms in 4.48 L of `CO _(2)` at S.T.P.
`= ( 3 xx 4.48 xx 6. 02 xx 10 ^(23))/( 22.4) = 4. 816 xx 10 ^(23)`
