The heat of solution for NaOH is -445.1kJ/mol. In an experiment, 5.00g of NaOH is completely dissolved in 1,000g of 20.0°C water in a foam cup calorimeter. Calculate
the final temperature of the water. (Cwater = 4.18 J/gx°C and NaOH is 40.0g/mol) plz show work

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
