Homework Help: Constant pressure calorimetry

  1. Nov 5, 2008 #1
    1. The problem statement, all variables and given/known data
    what mass of water could be warmed from 23.8 C to 46.3 C by a 100 g metal pellet at
    116 C

    2. Relevant equations

    3. The attempt at a solution
    well i know the formula qsurr=ms[tex]\Delta[/tex]T
    so qwater=ms[tex]\Delta[/tex]T

    but then how do i work my way around when the heat capacity isn't also given
    i'll really appreciate all the help i can get.

    Is this for a lab? I would imagine that such a procedure is utilized to find the heat capacity of an unknown metal however for this you would need the mass of water.

    Without metal heat capacity question has no solution. But I doubt you gave us all information regarding the question. Are you given any information about the metal? Molar mass? Is there a table with heat capacities of various metals somewhere in the book?
