200 `cm^(3)` of `N_(2)` gas is collected over water at `20^(@)C` and 730 mm pressure. At this temperature, aqueous tension is 14.20 mm. what is the mass of `N_(2)` gas collected?

Text Solution

Verified by Experts

`p_(N_(2))=(730-14.20)mm" "Hg=0.9418 atm`
`p_(N_(2)) xxV_(N_(2)) =nRT or, 0.9418xx0.2=(w)/(28)xx0.0821xx293`
`therefore w=0.219g`
