Question

Use the given information to solve the following problems.


1) In the lab you have an unknown

compound containing only the elements C,H,Cl, and O. Combustion analysis of a 40.10 g sample of the compound yields 58.57 g of CO2 and 14.98 g of H2O. A different sample of the same compound with a mass of 75.00 g is found to contain 22.06 g of Cl through gravimetric analysis. Determine the mass percent of each element present in the unknown compound.


2) Use your answer to #1 to determine the empirical formula of the compound.


3) The compound from #2 is found to have a molar mass of 9522 g/mol. Determine the molecular formula for this compound.
