Calculate :
Calculate the number of molecules in 4.4 gm of `CO_(2)`. [Atomic mass of C = 12,0 = 16]

A

`1.2xx10^(23)`

B

`6xx10^(22)`

C

`6xx10^(23)`

D

`12xx10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
A
1 mole of `CO_(2)=44g` of `CO_(2)`
`=6.023xx0.1xx10^(23)` molecules
`=6.023xx10^(22)` molecules
`=6.023xx10^(22)` molecules of ` O_(2)`
`=2xx6.023xx10^(22)` atoms of O
`~~1.2xx10^(23)`atoms of O
