Question:

This problem illustrates how combustion can be used to determine the molecular formula of an unknown compound. A compound X (8.00 mg) undergoes combustion in a stream of oxygen to give 24.60 mg of CO₂ and 11.51 mg of H₂O.

(a) Calculate the mass of carbon and hydrogen in X.

(b) How many moles of H are present in X per mole of C? Express this as a formula C₁H_x.

(c) Multiply this formula by successive integers until the amount of H is also an integer. This is the molecular formula of X.
