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$$\Delta$$T
so qwater=ms$$\Delta$$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.

no its actually a problem in the book

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?
