what is the final temp of the combination when 50 grams of chromium at 15 degrees celcius is added to 25 milliliters of water at 45 degrees celcius?

Answer 1

Note the correct spelling of celsius.
[mass Cr x specific heat Cr x (Tfinal-Tinitial)] + [mass water x spcific heat water x (Tfinal-Tinitial) = 0
Solve for Tfinal.
Post your work if you get stuck.

Answer 2

(50g)(0.107 cal/g degreesC)(tfinal-15C) +(25g)(1.000 cal/g degreesC)(tfinal-45C) is this correct
