When solid sodium hydroxide dissolves in water, the δh for the solution process is −44. 4 kj/mol. If a 13. 9 g sample of naoh dissolves in 250. 0 g of water in a coffee-cup calorimeter initially at 23. 0 °c. What is the final temperature of the solution? assume that the solution has the same specific heat as liquid water, i. E. , 4. 18 j/g·k.
