A sample of metal has a mass of 1.75 kg and a specific heat of 0.115 cal/g oC. What is the temperature change of the metal after 625 calories of heat are added?

My answer is 3 oC.
Just want to make sure is right and my equation is set up right.

    Why are you throwing away the rest of the number? I'm sure they showed on your calculator but you ignored them. You're allowed 3 places and you reported only 1.
    My answer is 3.10559 which I would round to 3.11 to three s.f. Your set up must be ok.
