  1. At STP, 1 mol = 22.4L
    convert liters of C8H16 gas to moles
    then, convert to moles of H2O by the mole ratio (look at the coefficients)

  2. thank you but I got 4.00 and it's incorrect.
    11.2LC8H16/22.4L=.5
    1mol/.5=8mol/x
    .5*8=4

  3. O2 is the limiting reagent so convert the moles of C8H16 to moles of O2 and then convert the moles of O2 to moles of H2O
