If we assume you meant 0.55mol tellurium, we get an empirical formula of K2TeO3.

Explanation:

We divide thru by the SMALLEST molar quantity, that of tellurium, to get an empirical formula.

Moles of tellurium = 0.55mol0.55mol=1

Moles of potassium = 1.10mol0.55mol=2

Moles of oxygen = 1.65mol0.55mol=3

And thus the empirical formula is K2TeO3.

All I have done is to divide thru by the SMALLEST MOLAR QUANTITY.
