a level isaac chemistry question

hi so i've been doing this question and i got -225JK-1mol-1, but apparently that's wrong according to the isaac physics website? i've tried -230 as well but to no avail. any help or clarity w the question below would be greatly appreciated, thanks.

'''
The free energy change of formation of iodine(III) chloride is −22.3kJmol−1 at 298K. Given that the enthalpy of formation is −89.5kJmol−1, find the standard entropy change on formation of 1mole of iodine(III) chloride from its elements in their reference states at 298K.
