Answer:

Explanation:

To calculate percent composition, we divide the experimentally derived mass of each element by the overall mass of the compound, and then convert to a percentage:

%C=

12.04g compound

7.34g C

×100%=61.0%

%H=

12.04g compound

1.85g H

×100%=15.4%

%N=

12.04g compound

2.85g N

×100%=23.7%

The analysis results indicate that the compound is 61.0% C, 15.4% H, and 23.7% N by mass.
