Write and balance the equation.
2C8H18 + 25O2 ==> 16CO2 + 18H2O
convert 570 gh C8H18 to mols. mol = g/molar mass octane.
Using the coefficients in the balanced equation convert mols octane to mols O2.
Now convert mols O2 to grams. g = mols x molar mass.
how many grams of oxygen are required to burn completely 570g of octane?
