The number of carbon monoxide molecular ...

The number of carbon monoxide molecular present in 1 `dm^3` at N.T.P. is _________ .

A

`6.02xx10^(23)`

B

`6.02xx10^(22)`

C

`0.269xx10^(22)`

D

`2.69xx10^(22)`

Text Solution

Verified by Experts

The correct Answer is:
D
22.4 `dm^3` of 'CO' contains `6.02xx10^(23) ` at N.T.P.
Hence number of CO molecules present in
1 `dm^3` at N.T.P `=(6.02xx10^(23))/(22.4) = 2.69 xx10^(22)`
