A 1.25-g sample of a compound containing only C,H, and O is analyzed by complete combustion of CO2 and H2O and is found to form 1.45g of CO2 and 0.592g H2O. Find the empirical formula of the compound. In a seperate measurement the molecular weight is found to be 153. Find the molecular formula of the compound.
A) amount of C in sample_____
B) amount of H in sampe______
C) mass of O in sample_______
D) amount of O in sample_______
E) emperical formula_______
F) molecular formula_______
can i get a clue on where to start please?
CxHyOz + O2 ------> CO2 + H2O
do i use the mass composition formula for C?
