Some solutes have large heats of solution, and care should be taken in preparing solutions of these substances. The heat evolved when sodium hydroxide dissolves is 44.5 kJ/mol. What is the final temperature of the water, originally at 20.0°C, used to prepare 1.25 L of 6.00 M NaOH solution? Assume that all the heat is absorbed by 1.25 L of water, specific heat 5 4.18 J/g · °C.
We need at least 10 more requests to produce the solution.
