Question

In the combustion of butane (`"C"_4"H"_10`), how many moles of oxygen are required to completely combust 5.26mol of butane?

Answer 1

`n("O"_2)=34.19"mol"~~34.2"mol"`

Explanation:

`2"C"_4"H"_10+13"O"_2->8"CO"_2+10"H"_2"O"`

`[(n("C"_4"H"_10),:,n("O"_2)),(2,:,13)]`

`n("O"_2)=5.26*13/2=34.19"mol"~~34.2"mol"`
