Answer to Question #309378 in General Chemistry for Nikki

Question

A compound is composed of 5.045g of carbon, 0.847g of hydrogen and 3.36g of oxygen. Find the empirical formula for this compound knowing that H = 1g/mole , O = 16g/mole and C =12 g/mole.

Answer 1

$\begin{matrix} &C&H&O\\moles&\frac{5.045}{12}&0.847&\frac{3.36}{16} \\ratio&2.00&4.03&1.00\\mole\>ratio&2&4&1 \end{matrix}$

Empirical Formula$=C_2H_4O$
