if 158 grams of silver at a temperature of 98.5 degrees celcius is placed in a styrofoam cup of 85 grams of water at 13 degrees celcius, what would the final temperature of the water be in two minutes

• calorimetry -

mass Ag x specific heat Ag x (Tfinal-Tinitial) + mass H2O x specific heat water x (Tfinal-Tinitial) = 0
Substitute the numbers and solve for the only unknown, Tfinal. However, I don't know that this will occur in two minutes.
By the way, note the correct spelling of celsius.
