Styrene, the building block of polystyrene, consists of only $\mathrm{C}$ and $\mathrm{H}$. If $0.438 \mathrm{g}$ of styrene is burned in oxygen and produces $1.481 \mathrm{g}$ of $\mathrm{CO}_{2}$ and $0.303 \mathrm{g}$ of $\mathrm{H}_{2} \mathrm{O},$ what is the empirical formula of styrene?

Step 1

From the given information, we know that $1.481 \mathrm{g}$ of $\mathrm{CO}_{2}$ is produced. The molar mass of $\mathrm{CO}_{2}$ is $12.01 + 2(16.00) = 44.01 \mathrm{g/mol}$. Therefore, the moles of $\mathrm{CO}_{2}$ produced are: $$\frac{1.481 Show more…
