an unknown solid substance weighs 121g. calculate the specific heat if 425.2 cal raise the temperature of the solid from 24.0 degrees C to 55.7 degrees C.

  • gen. chemistry -

    q=mC∆T

    ∆T=55.7ºC-24.0ºC
    m=121g
    q=425.2
    C=specific heat=?

    Plug in the values and solve.
    C=q/m∆T
