Determine the final temperature when 10g of steam at 100C mixes with 500g of water at 25C.

I have 4.184x 10(100-x) + 40700 x 10= 500 x (x-25) x 4.18.

The book has 10/18 instead of 10 on left hand side of equation. Why??

  • chemistry -

    I expect the 18 is to convert 10 g H2O to mols since the 40700 is in J/mol and not J/g.
