1a) Consider the reaction: C12H22O11(s)+12O2(g)→12CO2(g)+11H2O(l) in which 10.0 g of sucrose, C12H22O11, was burned in a...
1a) Consider the reaction: C12H22O11(s)+12O2(g)→12CO2(g)+11H2O(l) in which 10.0 g of sucrose, C12H22O11, was burned in a bomb calorimeter with a heat capacity of 7.50 kJ/∘C. The temperature increase inside the calorimeter was found to be 22.0 ∘C. What is the heat of this reaction per mole of sucrose? 1b) One tablespoon of peanut butter has a mass of 17.0 g.

Calorimetry can also be used to determine nutritional Calories, which are actually kilocalories. One (1) nutritional Calorie = 1000 calories, and 1 calorie = 4.184 J. When 1.0 g of a snack cake is combusted in a constant-volume bomb calorimeter with a heat capacity (including its water) of 10.0 kJ/°C, the temperature of the calorimeter rises by 1.88°C. How many nutritional calories (Calories) are in one serving (28 g) of this snack cake? Enter your answer to three significant figures...
