Question
What is the empirical formula, and what is the percent composition of dimethylhydrazine, $\mathrm{C}_{2} \mathrm{H}_{8} \mathrm{N}_{2},$ a colorless liquid used as a rocket fuel?
Step 1
We can simplify this to an empirical formula by dividing all the coefficients by their greatest common divisor, which in this case is 2. This gives us the empirical formula $\mathrm{CH}_{4} \mathrm{N}$. Show more…

Percent Composition and Empirical Formulas
Dimethylhydrazine is a carbon-hydrogen-nitrogen compound used in rocket fuels. When burned in an excess of oxygen, a $0.312 \mathrm{g}$ sample yields $0.458 \mathrm{g} \mathrm{CO}_{2}$ and $0.374 \mathrm{g} \mathrm{H}_{2} \mathrm{O}$. The nitrogen content of a $0.486 \mathrm{g}$ sample is converted to $0.226 \mathrm{g} \mathrm{N}_{2} .$ What is the empirical formula of dimethylhydrazine?
What is the empirical formula of a compound whose percentage composition is found to be 2.20% hydrogen 26.7% carbon and 71.1% oxygen?
