The temperature rise is 110C.
Multiply that by the mass and specific heat.
You may have to convert joules to kilojoules. I assume you know how to do that

Thank you, I've done this and submitted it only keep getting it incorrect, so I was wondering what I could be doing wrong.
Thank you

Unless you shown your work I cannot advise on where you might have made a mistake, or if perhaps the "answer book" number is wrong.
Remember that they are asking for the answer in kilojoules, not joules. Use three significant figures
