Answer to Question #24950 in Other Chemistry for jordan
How many moles of oxygen are needed to burn 9.3 moles of butane in this combustion reaction?
The chemical equation for the burning reaction is
2C4H10 + 13O2 = 8CO2 + 10H2O
According to the chemical equation
n(O2) = n(C4H10) : 2 x 13 = 9.3 : 2 x 13 = 60.45mol
Answer: n(O2) = 60.45 mol
