Question

explain the second question that says "using the molar heat of solution above"  molar mass of NaOH is 39.997g/mol

Using the molar heat of solution provided in the question above: determine how many g solid sodium hydroxide you must add to 500. mL of water at 18.2 degrees Celsius in order to change the water temperature to 33.8 degrees Celsius.
Transcribed Image Text:Using the molar heat of solution provided in the question above: determine how many g solid sodium hydroxide you must add to 500. mL of water at 18.2 degrees Celsius in order to change the water temperature to 33.8 degrees Celsius.
The molar heat of solution (AHsoln) of sodium hydroxide is -445.1 kJ/mol. In a certain experiment, 5.00 g of solid sodium hydroxide is completely dissolved in 1.000 L of 20.0°C water in a foam cup calorimeter. Assuming no heat loss, calculate the final temperature of the water.
