A researcher studying the nutritional value of a new candy places a 4.70 g 4.70 g sample of the candy inside a bomb calorimeter
Sauron [17]

Answer : The nutritional Calories per gram of the candy are, 5.36 calories

Explanation :

First we have to calculate the amount of heat.

q=c\times \Delta T

where,

q = heat = ?

c = specific heat = 43.90kJ/K

\Delta T = change in temperature = 2.41^oC=2.41K

Now put all the given values in the above formula, we get:

q=43.90kJ/K\times 2.41K

q=105.799kJ

Now we have to calculate the heat for per gram of sample.

Heat = \frac{105.799kJ}{4.70g}=22.51kJ/g=22510J/g

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 = \frac{22510J}{4.2J}\times \frac{1}{1000}cal=5.36cal

Therefore, the nutritional Calories per gram of the candy are, 5.36 calories
