When 33.5 mL of 0.580 M H2SO4 is added to 33.5 mL of 1.16 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate ?H of this reaction. (Assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as for pure water.)
calculate the resulting molarity when 50.0ml of 2.13M sodium Chloride solution is mixed with 80.0ml of 1.45M
