    Explanation:

    C4H10 + 13/2O2 ———> 4CO2 + 5H2O

    so u can work out the amount of moles by doing

    moles=mass/mr

    mr of C4H10 is 12 × 4 + 10 =58

    =7.269/58

    = 0.125moles

    Then u can use the molar ratio which is

    6.5:4

    0.125 ÷6.5 × 4 = 0.0769moles

    hope this helps:)
