The compound known as diethyl ether, commonly referred to as ether, contains carbon, hydrogen, and oxygen. A 3.626 g sample of ether was combusted in an oxygen rich environment to produce 8.612 g of CO2(g) and 4.406 g of H2O(g). Insert subscripts to complete the empirical formula of ether.

Explanation:

Hello,

In this case, the first step is to compute the moles of carbon in the sample that are contained in CO2 only at the products as shown below:

Next the moles of hydrogen contained in the H2O only:

Now, we compute the mass of oxygen in the sample, by subtracting mass of both carbon and hydrogen from the 3.626 g of sample:

And the moles:

Now, the mole ratios by considering the moles of oxygen as the smallest:

Thus, empirical formula is:
