Hey whats up,(adsbygoogle = window.adsbygoogle || []).push({});

I am stuck on the following problem.

a copper pot with mass of 0.5kg contains 0.170kg of water at a temperature of 20C. A 0.250kg block of iron at 85C is dropped into the pot. Find the final temperature assuming not heat loss.

Ok, so Here is what i was thinking about doing:

Qwater + Qiron + Qcopper = 0

i know the initial temperature of the system, 20C. i also know the temp of the Iron block. so...How do i find the final T? Q = mc(Delta T), the delta T part is where im confused. How do i set up the equation so i can solve for Tfinal? Thanks for any help.
