Question
Chapter 6, Problem 19P
Interpretation Introduction
Interpretation:
The number of Calories from the two different samples needs to be determined and more Caloric product needs to be determined.
Concept Introduction:
Caloric values of different types of food can be stated as below.
Protein: 4000 cal/g = 4 Cal/g
Carbohydrate: 4000 cal/g = 4 Cal/g
Fat: 9000 cal/g = 9 Cal/g
The total Caloric value of the sample should be calculated using above relationships.

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
