    M = mass of metal

    M = mass of water

    c = specific heat

    c of water = 1 cal/g * C

    use the formula

    Q = mcΔT = McΔT

    (27g) * (c) * (107 C - 27.3 C) = (54.2g) * (1 cal/g * C) * (27.3 C - 22 C)

    2152 * c = 287.26

    c = specific heat of metal =.133 cal/g * C

    1 cal / 4.186 j/g * C =.133 cal / x

    =.557 J/g * C
