Homework Statement


what mass of water could be warmed from 23.8 C to 46.3 C by a 100 g metal pellet at
116 C

Homework Equations





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?
