To determine the amount of a hypothetical compound KHA · H2A 2H2O in a pure sample, Senku asked his friend Chrome to titrate it with 0.100M NaOH. Unfortunately, an accident occurred while he was away and all of the 50.0 mL NaOH solution was mixed into the sample. To remedy the situation, Senku decided to perform back titration with a 2.375 mL of 0.0800M H2SO4 solution. a) How many excess moles of NaOH were added to the solution? b) How many moles of the compound KHA·H¿A-2H2O are present in the sample? c) When the reaction between the same sample of KHA:H2A•2H2O and NaOH was carried out in a coffee cup calorimeter, the measured total temperature rise from 25.0°C was 54.0°C. Determine the magnitude of the heat of the neutralization of KHA·H»A•2H2O and NaOH in Joules. Assume that the Cp of the solution is 18.0 cal/mol-K. (
