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
