Finding the Heat Capacity of a Metal Using Constant Pressure Calorimetry

AI Thread Summary
To find the heat capacity of a metal using constant pressure calorimetry, the mass of water that can be warmed by a 100 g metal pellet at 116 C is being calculated. The relevant formula is q = msΔT, where q represents heat transfer, m is mass, s is specific heat capacity, and ΔT is the change in temperature. The discussion highlights the challenge of solving the problem without the heat capacity of the metal being provided. Participants suggest that additional information, such as the molar mass of the metal or a reference table of heat capacities, may be necessary to complete the calculation. The problem emphasizes the importance of having all required data for accurate thermal calculations.

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\DeltaT
so qwater=ms\DeltaT

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?

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
