25g of a breakfast cereal contain 110 calories. How many calories are released per gram? Convert the answer above to joules.
To find out how many calories are released per gram, you need to divide the total number of calories by the total weight of the cereal.
Step 1: Calculate calories per gram:
Total calories = 110
Total weight = 25 grams
Calories per gram = Total calories / Total weight
Calories per gram = 110 calories / 25 grams
Calories per gram = 4.4 calories per gram
To convert calories to joules, you can use the conversion factor that 1 calorie is equal to 4.184 joules.
Step 2: Convert calories to joules:
Calories = 4.4 calories per gram
Joules = Calories x Conversion factor
Joules = 4.4 calories per gram x 4.184 joules per calorie
Joules = 18.37 joules per gram
Therefore, the answer is that 25g of the breakfast cereal release approximately 4.4 calories per gram or 18.37 joules per gram.
