Answer 1

Answer:

9.24%

Explanation:

Quantity of the compound  = 0.66g (Given)

Quantity of the Nitrogen released = 112ml (Given)

According to the Dumas method -

Percentage of Nitrogen will be calculated as -

= Volume of Nitrogen at STP/ 8 × mass of the organic compound  

= 112/ 8 * 0.66  

= 9.24 %

Therefore, the percentage of Nitrogen will be 9.24%
