Calculate the number of atoms of oxygen ...

Calculate the number of atoms of oxygen present in 176g of `CO_(2)`

A

`2.408 xx 10^(26)`

B

`4.816 xx 10^(23)`

C

`1.204 xx 10^(22)`

D

`4.816 xx 10^(24)`

Text Solution

Verified by Experts

The correct Answer is:
D
No. of moles of `CO_(2)=(176)/(44)=4`
`therefore` No. of mole of O atom= `4 xx 2=8`
`therefore` No. of O atom `=8 xx N_(A)`
`=8 xx 6.023 xx 10^(23)`
`=48.184 xx 10^(23)`
