It looks correct to me perhaps they want it in the form of 4 sf and expoential form?

Dear ahawk1;

I got first another MW for decaborane, and second really another left over.

You may try the Diagram with your corrected data and you will easily get the correct answer:

"Stoichiometry Problem (#23'025) (http://www.chemicalforums.com/index.php?topic=23025.0)"

Therein is also an Example Diagram:  How to do a "Stoichiometry Problem".

Good Luck!
