0.246 g of the organic compound gave 22....

0.246 g of the organic compound gave `22.4 cm^(3)` of nitrogen gas at STP as determined by Dumas method. The percent of nitrogen in the compound is

A

`11.38`

B

`17.07`

C

`22.76`

D

`34.14`

Text Solution

Verified by Experts

The correct Answer is:
A
% of `N=("Vol. of "xx N_(2))/("wt.of org. comp").(28)/(22400).100`
`=(22.4)/(0.246).(28)/(22400).100=11.38%`
