how many moles of ethylene reacted if 0.50 mole of water is produced.
C2H4 + 3O2 --- 2CO2 + 2H2O

• chemistry -

0.5 mole H2O x (1 mol C2H4/2 mol H2O) = ??
Note that the factor (the part in parentheses) is just the ratio of the coefficients in the balanced equation. Also, note that the factor is placed so that the unit we are converting FROM cancels (in this case it is H2O) and the unit we are converting TO is the unit we keep.
