M&M candies consist of 70% carbohydrates, 21% fats and 4.6% protein as well as other ingredients that do not have caloric value. What quantity of energy transfer would occur id 34.5g M&Ms were burned in a bomb calorimeter.
34.5(.7*4+.21*9+.046*4)= >>> about 170 calories
To calculate the quantity of energy transferred when 34.5g of M&M candies are burned, we need to consider the energy content of each macronutrient (carbohydrates, fats, and proteins) present in the M&Ms.
First, we'll convert the percentages into grams:
Carbohydrates: 70% of 34.5g = 0.70 * 34.5g = 24.15g
Fats: 21% of 34.5g = 0.21 * 34.5g = 7.245g
Protein: 4.6% of 34.5g = 0.046 * 34.5g = 1.587g
Next, we need to know the energy content of each macronutrient per gram:
Carbohydrates: 4 calories per gram
Fats: 9 calories per gram
Protein: 4 calories per gram
To determine the total energy transferred, we need to calculate the energy from each macronutrient and sum them up:
Energy from carbohydrates = 24.15g * 4 calories/g = 96.6 calories
Energy from fats = 7.245g * 9 calories/g = 65.205 calories
Energy from protein = 1.587g * 4 calories/g = 6.348 calories
Total energy transferred = Energy from carbohydrates + Energy from fats + Energy from protein
Total energy transferred = 96.6 calories + 65.205 calories + 6.348 calories
Total energy transferred = 167.153 calories
Therefore, if 34.5g of M&Ms were burned in a bomb calorimeter, the quantity of energy transferred would be approximately 167.153 calories.
