Can u guys check my answer??

Question: convert 24 grams of ice at -10 degrees Celsius to water at 45 degrees Celsius.


I got q= 13022 joules

Is that correct?

  • Chem -

    I don't think so. Post your work and I'll look for the error.

  • Chem -

    Q=24.0g (2.03j/gc) (10c)
    Q=334j/g(24g)
    Q=24g(4.184j/gc)(45c)

    Added them and got q= 13022j

  • Chem -

    24.0(2.03)(10) = 487.2
    4518.7
    487.2 + 4518.7 = ??about 5,000+

  • Chem -

    But 334 x 24= 8016

  • Chem -

    Oh oops I see where u got the 4518.7 but don't u also have to add the middle equation??
