The sum of the heats gained is zero (some will be negative, as in heat lost).
heat gained calorimeter=masscalor*ccu*(Tf-273)
heat gained by water= (masswater+massmelted ice)*cw*(tf-0)
heat gained by ice= Hf(massice)
Heat gained by lead=masslead*clead*(tf-(417+273))
add all these, set to zero, and solve for Tf.
I'm putting in the answer I get but the website that I do the homework on says the answer is wrong. I'm getting 94.77 K for final temperature, but it says that's wrong. What should I do?
I would recheck it. You know it cant be 94Kelvin. That is pretty cold.
