Calculating the volume of O2?

Update:

Sugars react with oxygen in our cells to produce CO2, H2O and energy. Calculate the volume of O2 required for the complete combustion of 75g glucose, C6H12O6, to CO2 and H2O at STP?

Update 2:

I really don't know where to begin. Help would be greatly appreciated!

    C6H12O6 + 6 O2 → 6 CO2 + 6 H2O

    (75 g C6H12O6) / (180.1559 g C6H12O6/mol) x (6 mol O2 / 1 mol C6H12O6) x (22.414 L/mol) =

    56 L O2 at STP
