First, make sure the equation is balanced. Next, can you find the number of moles of whatever substance you have? Use this: http://www.ptable.com/

There is no equation. It's adding different molarities of the same kind of solution.

Ohh I didn't realize it's the same chemical. Ah well, use the formula n=mV to get the number of moles. Then add them up and divide by the total final volume.
