a. Combustion analysis of a 13.42-{\rm g} sample of estriol (whichcontains only carbon, hydrogen, and oxygen) produced 36.86 g{\rm{CO}}_2 and 10.06 g {\rm{H}}_2 {\rm{O}}. The molar mass ofestriol is 288.38 g/mol.

b. Find the molecular formula for estriol.
Express your answer as a chemical formula.

Can you tell me what formulas and the approach to use (exactly whatI need to do)?

Combustion analysis of a 12.01-{\rm g} sample of tartaric acid-which contains only carbon, hydrogen, and oxygen-produced 14.08 {\rm g} {\rm{CO}}_2 and 4.32 {\rm g} {\rm{H}}_2 {\rm{O}}. Find the empirical formula.

The following data were obtained from experiments to find the molecular formula of lidocaine, a local anesthetic, which contains only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of a 3.54-{\rm g} sample of lidocaine with excess {\rm{O}}_2 formed 9.32 g {\rm{CO}}_2 and 3.00 g {\rm{H}}_2 {\rm{O}}. Another sample of mass 2.35 {\rm g} was found to contain 0.281 g of {\rm N}. The molar mass of lidocaine was found to be 234. Find the molar formula of lidocaine.
