put this solution on YOUR website!Note:

= 1st chem. rxn

= 2nd chem. rxn

= 3rd chem. rxn.

= Oxygen produced by each rxn.
1st condition:

produces twice that of

-------->

-------->

2nd condition:

produces twice that of

-------->

NOW, equating the 3 values of the chemical rxn that has combined total of 560cc

--------------------> working eqn

----------------> amount of Oxygen produced by

FOR

=

FOR

=

In doubt? Go back working eqn,

, note: cc= cubic centimeter=
