Answer:
92.96%
Explanation:
mass percent = mass of element in compound
----------------------------------------------- x 100
mass of compound
example: N2H2
mass percent = 2 x (mass of nitrogen)
------------------------------------------------------------------- x 100
2 x (mass of nitrogen) + 2 x (mass of hydrogen)
plug the masses in....
mass percent = 2 x 14.0067
--------------------------- x 100
( 2 x 14.0067 ) + (2 x 1)
once you do the math, your answer comes out to 92.96% :) , hope this helps!
