Problem: If 1.5 mol C2H5OH, 1.5 mol C3H8, and 1.5 mol CH3CH2COCH3 are completely combusted in oxygen, which produces the least number of moles of H2O? Explain.

FREE Expert Solution

For C2H5OH, the balanced combustion reaction is:

C2H5OH + 3 O2 → 2 CO2 + 3 H2O

mol H2O=1.5 mol C2H5OH(3 mol H2O1 mol C2H5OH)=4.5 moles
