IF YOUR MASTERING CHEM QUESTION IS THIS: One tablespoon of peanut butter has a mass of 17 g . Its combusted in a calorimeter whose warmth capability is 110 kJ/C . The temperature of the calorimeter rises from 22.3 C to 25.6 C.
ANSWER:
5.1 Cal/g
25.2-22.5 = 2.7 C
130 kJ/C x 2.7 C x 1000 J/kJ = 351,000 J
351,000 J / 4.184 J/cal = 83,900 cal
1000 energy = 1 meals Calorie
83.9 meals energy / 17 g = 4.93 meals energy/gram
