Compound Z is a chemical naturally found in peppermint and other mint plants and has mild anesthetic properties. In a combustion analysis experiment, 95.6 mg of Compound Z (molar mass = 156 g/mol) are burned in oxygen gas to give 269 mg CO2 and 110 mg H20. What is Compound Z's empirical formula? Write the numbers that you would write in the subscript of the formula in the boxes next to the symbol of the element.

A molecular formula expresses the number of each kind of atom in a molecule. For example, the molecular formula for propene, C3H6C3H6, indicates three carbon atoms and six hydrogen atoms per molecule. This also means that one mole of propene contains three moles of carbon and six moles of hydrogen.An empirical formula expresses the mole ratio of the elements. The empirical formula for propene is CH2CH2, indicating twice as much hydrogen as carbon. When analyzing unknown compounds in a lab, it is often possible to identify the mole ratios, and thus the empirical formula, but not the molecular formula.Notice that the molecular mass of propene, 3(12)+6(1)=42amu3(12)+6(1)=42amu, is a multiple of the empirical formula mass, 1(12)+2(1)=14 amu An unknown compound contains only carbon, hydrogen, and oxygen (CxHyOzCxHyOz).
