If a 45kg sample of water absorbs 345kj of heat. If the water was initially at 22.1 degrees Celsius, define what is the final temperature?
what volume in milliliters of a 0.141 solution is required to reach the endpoint in the complete titration of a 16.0
41.89 mL of NaOH were required to completely titrate 25.00 mL of a weak monoprotic acid. After 11.90 mL of sodium hydroxide had been added to the solution, the pH of the solution was 6.81. Calculate K_a_ and pK_a_ for this weak acid.
