How do you find the relative abundance and the isotopic mass of an element? Zirconium has four naturally occuring isotopes.
90 = amu 89.905 and % 51.45
91 = amu 90.906 and % 11.22
92 = amu 91.905 and % 17.15
94 = amu ?? and % ??

I need to know the relative abundance and the isotopic mass and how to reach the answer.

I know that the equation is set up like this:
91.224 = 89.905(.5145) + 90.906(.1122) + 91.905(.17.15) + x(1-.5145 + .1122 + .1715).
I just don't understand how to do the math. I keep coming up with different answers every time. I haven't had algebra for two years so I'm not sure what to do with the x.

I am taking O-chem right now and need to remember some of the basic stuff from general chemistry such as finding molarity, pH, etc etc.
Unfortunately, I took general chemistry freshman year and I am now a senior, so everything is a little rusty.

Any basic websites with formulas/tips etc will be greatly appreciated. Best one gets the 10 points!
