The octane rating of gasoline is a relationship of the burning efficiency of the given gasoline mixture to the burning efficiency of octane (C8H18). (Figure 1) Like most hydrocarbons, octane reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is C8H18(g)+O2(g)→CO2(g)+H2O(g)
PROBLEM BELOW:
Balanced chemical equation
2C8H18(g)+25O2(g)→16CO2(g)+18H2O(g)
0.310 mol of octane is allowed to react with 0.870 mol of oxygen
Part C
How many moles of water are produced in this reaction?
Express your answer with the appropriate units.
Part D
After the reaction, how much octane is left?
Express your answer with the appropriate units.
