Mass of `CO_(2)` is 88 g. The number of atoms of oxygen present is :

Options

A. `2.41 xx 10^(24)`
B. `1.2 xx 10^(23)`
C. `1.4 xx 10^(23)`
D. `2.41 xx 10^(23)`

Answer

A

Explanation

44.0 grams of `CO_(2)` contain oxygen atoms
`= 2xx 6.022 xx 10^(23)` atoms
88.0 grams of `CO_(2)` contain oxygen atoms
`= 2 xx 2 xx 6.022 xx 10^(23)`
`=2.41 xx 10^(24)` atoms.
