How many liters of pure oxygen at STP is consumed by a human being in 24
hours if the human body requires daily energy that comes from metabolizing
816 grams of sucrose (C12H22O11)?
C12H22O11(s ) + 12 O2(g) => 12 CO2(g)+11 H2O

816 g C12H22O11 = how many moles? mol = g/molar mass.
Convert mol sucrose to mols O2 using the coefficients in the balanced equation.
Convert mol O2 to volume. mol O2 x 22.4 L/mol = ?L.
