Answer : The nutritional Calories per gram of the candy are, 5.36 calories
Explanation :
First we have to calculate the amount of heat.

where,
q = heat = ?
c = specific heat = 
= change in temperature = 
Now put all the given values in the above formula, we get:


Now we have to calculate the heat for per gram of sample.
Heat = 
Now we have to calculate the heat in terms of calories.
As, 1 nutritional Calories = 1000 calories
and, 1 calories = 4.2 J
As, 4.2 J = 1 calories
So, 22510 J = 
Therefore, the nutritional Calories per gram of the candy are, 5.36 calories
