What is the Final Temperature of the Mixture?

  1. Nov 4, 2015 #1
    1. The problem statement, all variables and given/known data
    Assuming no heat loss to the container or the environment, what is the final temperature (K) of a mixture of 9.28L of liquid 1 (density=1070kg/L & specific heat capacity of 4358J/kg/K) at 378K and 12.15L of a second liquid (density=1070kg/L & specific heat capacity of 1776J/kg/K) at 296K?

    2. Relevant equations
    I believe it should be cmΔT=cmΔT

    3. The attempt at a solution
    I came up with (cH)(mH)(TH-TM)=(cL)(mL)(TM-TL)
    H= Mixture with higher temp
    M=The middle temp we are looking for
    L= Mixture with lower temp

    Yeah, but what's the answer to the question?

    Also, isn't a liquid with a density of 1070 kg/L rather heavy? You'd need a crane to pick up a cupful of this stuff.
