Answer 1

Answer:-

Firstly total amount of heat released is calculated by using the simple formula and then calories per gram is calculated.

The answer is given in the image,

Answer a mass of candy=6.00g. Cecel = 37-2613-1-37-2k18-1 11=2-23°C Heat released - Cecel. AT = 31,2x2.23 = 82.96 KJ - 82-961031 4, 18 Joule = 4 colo Heart = 82-96X163 4.18 = 19.85x103 cal Calories per green of Candy = 19.85*10* 6.00 = 3.31 X169 Calla.
