If there is a question here I don't see it.
If 1.30g of steam at 100.0 ∘C condenses into 40.0g of water, initially at 31.0∘C, in an insulated container, what is the final temperature of the entire water sample? Assume no loss of heat into the surroundings.
Remember you get faster service if you don't post piggy back. Go to the top of the page and post your own question all by itself.
heat lost by steam + heat lost by 1.3g liquid H2O + heat gained by 31 degree H2O = 0
[mass steam x -heat vap] + [mass steam to H2O x specific heat H2O x (Tfinal-Tinitial)] + [mass cool H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Substitute and solve for T final. I get something like 49 C or so if I didn't goof. Post your work if you get stuck.
