I don't unerstand what I'm supposed to do for these

Heat = mass * c * temp change

175g 0.79J/gC 75 C

Heat = mass * c * temp change

352g 1.65J/gC 25 C

Heat = mass * c * temp change

268g 4.18J/gC 40 C

Heat = mass * c * temp change

74g 0.21J/gC 67 C

These are the answers I'm supposed to match with each one

1.04kJ

10.4kJ

14.5kJ

44.8kJ

    You just need to multiply the terms and transform to kj by dividing by 1000

    1) 10.4kj

    2) 14.5 kj

    3) 44.8 kj

    4) 1.04 kj

    and there you go.
