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. 4.4 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 x 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 6.92 xx 10^(23))/(22.4)`
= `4.816 xx 10^(23)`
