Thermodynamics in physics problem. A 200-g copper calorimeter contains 350 g of water at 25 C.? What is the mass of ice added at 0 Celsius if the final temperature of the system is 9 Celsius? thank you :)

Q lost = Q gained mc dT[water] - mc dT(ice) -0.35 x 4200 x (25-9) = m 2100 x (25-9) -23 520 = m 33600 0.7 = mass of ice i think thats right

I a freshman of Bupt in China.I am eager to help you.But I never see a physics problem in english .Just let me have a try. I think you can find the thermal capacity of copper ice and water.Then you can calculate the heat given out by the copper and water when their temperature fall from 25C to 9C.Then you can calculate you need how many ice of 0C to make the final temperature of the system 9C.The amount of heat given out and the amount absorbbed is the same. My English is just so-so,I'm sorry that if I didn't make myself understood
