What equation is the solution manual using to solve what the final temp of 50.7 g of water at 22C is after adding 20g of copper at 100C? assuming no energy is lost to surroundings

mc(delta)T=mc(delta)T
One for the water values and one for the copper values

You are assuming for this problem that the heat (q) lost by the water is equivalent to the heat (q) gained by the calorimeter (in this case the copper pot?) therefore you can use mc(delta)T=mc(delta)T to calculate the heat lost by the water and find the final temperature of the water.
