Isooctane (C8H18) is the principle component of gasoline.

Isooctane burns in the engine according to the following reaction:

2C8H18 + 25O2 → 16CO2 + 18H2O

 

How many mol of H2O are produced when 4.50 mol of C8H18 burns.

 

-----------------------------------------

 

C8H18 : H2O = 2 : 18 = 1 : 9 반응 비이므로,

C8H18 : H2O = 1 : 9 = 4.50 mol : ? mol

? = 9 * 4.50 = 40.5 mol

 

답: 40.5 mol H2O
