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?

Note the correct spelling of celsius.
[mass Cr x specific heat Cr x (TfinalTinitial)] + [mass water x spcific heat water x (TfinalTinitial) = 0
Solve for Tfinal.
Post your work if you get stuck. 
(50g)(0.107 cal/g degreesC)(tfinal15C) +(25g)(1.000 cal/g degreesC)(tfinal45C) is this correct
