hydrogen peroxide/ catalase -- investigating substrate concentration--- michaelis equation query?

I have come across a major stumbling block with my  kinetics (michaelis equation).  

Aim:    
I am investigating the changes of hydrogen peroxide concentration on the rate of decomposition of catalase.

Outline of method:
The apparatus involve yeast(catalase), hydrogen peroxide, a 100cm3 gas syringe to collect oxygen.  I am calculating the volume of gas collected in 30 seconds.  The concentrations I plan to do are 0.1M, 0.5M, 1M, 2M, 4M.  The concentration of the yeast is 10g of bakers yeast granules dissolved in 100g of water.

How do I predict using the michaelis equation the volume of oxygen collected for the 5 given concentrations?   in order which to make a prediction of the graph which should form a hyperbolic curve.  Please could you give an example of the complete working out for any given concentration, where necessary (if required) making up values of any data  I omitted.

Could you also explain how the units of concentration (Vol, % and M) relate to one another?
