Help please. I can't figure out this problem!!!

One of the steps in the purification of uranium ore involves the reaction of uranium(VI) oxide with bromine trifluoride

6 UO3(s) + 8 BrF3(l) → 6 UF4(s) + 4 Br2(l) + 9 O2(g)

How many grams of excess reactant remains after 8.88 grams of UO3 are reacted with 4.41 grams of BrF3?

[Hunter2]

Compare how much mole 1 UO₃ fits to BrF₃

Calculate the moles for the given reactants and compare again what is in excess.

The difference from the given value and the calculated value is the result.
