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

1.	The number of carbon monoxide molecular present in 1 dm^3 at N.T.P. is _________ .
Answer» `6.02xx10^(23)` `6.02xx10^(22)` `0.269xx10^(22)` `2.69xx10^(22)` SOLUTION :22.4 `dm^3` of 'CO' CONTAINS `6.02xx10^(23) ` at N.T.P. Hencenumber of CO MOLECULES PRESENT in 1 `dm^3` at N.T.P `=(6.02xx10^(23))/(22.4) = 2.69 xx10^(22)`
