A sample of liquid consisting of only C,H and O and having a mass of 0.5438g was burned in pure oxygen and 1.039g of CO2 and 0.6369g H2O were obtained. what is the empirical formula of the compound?
Convert g CO2 to g C.
Convert g H2O to g H.
0.5438g - g C - g H = g O
Convert grams of each to mols and find the ratio for the empirical formula. Post your work if you get stuck.
