Problem: Combustion analysis of a hydrocarbon produced 33.01 g CO2 and 13.52 g H2O.Calculate the empirical formula of the hydrocarbon.

FREE Expert Solution

Step 1:  There is 1 mole of C in 1 mole of CO2. Finding the moles of C:


MM of CO2 is 44.01


mole of C=33.01 g CO2×1 mol CO244.01 g CO2×1 mol C1 mol CO2

moles of C = 0.75 mol


There are 2 moles of H in 1 mole of H2O. Finding the moles of H:

 

MM of H2O is 18.02


moles of H=13.52 g H2O×1 mol H2O18.02 g H2O×2 mol H1 mol H2O

moles of H = 1.5 mol
