The number of oxygen atoms in 4.4 g of `CO_(2)` is approximately

A

`1.2xx10^(23)`

B

`6xx10^(22)`

C

`6xx10^(23)`

D

`12xx10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
A
44 g of `CO_(2)` has `2xx6xx10^(23)` atoms of oxygen
4.4 g of `CO_(2)` has `=(12xx10^(23))/44 xx4.4=1.2xx10^(23)` atoms.
