How many moles of butane do we need to produce 10 moles of CO2 by reaction with oxygen? I think the balanced equation is 2 C4H10 + 13 O2 -----> 8 CO2 + 10 H2O

I appears that we get 2/8 mole carbondioxide for each mole of butane

moles butane=10*2/0=20/8 moles=2.5 moles

oops typo
moles butane=10*2/8=20/8 moles=2.5 moles
