The combustion of 4.16 grams of a compound which contains only C,H,O and F yields 7.7 g CO₂ and 2.52 g H₂O. Another sample of the compound with a mass of 3.63 g is found to contain 0.58 g F. What is the empirical formula of the compound?

C₅H₁₀(l) + O₂(g) → CO₂(g) + H₂O(g)

A compound composed of carbon, hydrogen and nitrogen undergoes a combustion reaction to produce 264.21 g CO₂, 63.06 g H₂O and 46.4 g NO₂. Determine its empirical formula.

An unknown compound is composed of carbon, hydrogen and oxygen. A 4.30 g sample is ignited and creates 8.59 g CO₂ and 3.52 g H₂O. If the molar mass is 176.22 g/mol, what is the molecular formula?

In the presence of a small amount of oxygen a combustion reaction will not only produce carbon dioxide, but also carbon monoxide. The incomplete combustion of naphthalene, a hydrocarbon used in many dyes, produced 2.80 g CO, 4.40 g CO₂ and 1.44 g H₂O. Determine its empirical formula.
