Homework Statement
A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157 g of the compound produced 0.213 g CO2 and 0.0310 g H2O. In another experiment, it is found that 0.103 g of the compound produces 0.0230 g NH3. What is the empirical formula of the compound? Hint: Combustion involves reacting with excess O2. Assume that all the carbon ends up in CO2 and all the hydrogen ends up in H2O. Also assume that all the nitrogen ends up in the Nh3 in the second experiment.
Homework Equations
The Attempt at a Solution
What I have is
___+ O2 --> CO2 + H2O
___-->NH3
I got stuck after this. I wonder how a compound that contains C, H, N and O yields only NH3. where did C and O go?
Please help me. Thank you so much
