Step 1 A pound of candies contains ⋆96g of fat ⋆320g of carbohydrate ⋆21g of protein The mass of serving is m=42g Let us calculate the fuel value of one serving. First, we have to find the fuel value of candies per pound. Fat=96g⋅38kJg =3648kJ Carbohydrate=320g⋅17kJg =5440kJ Protein=21⋅17kJg =357kJ Total fuel value per pound = Fat + Carbohydrate + Protein =3648kJ+5440kJ+357kJ =9445kJ  per pound Step 2 Now, we will calculate the fuel value per gram. Total fuel value per gram = Total fuel value per pound⋅1lb453.6g =9445kJlb⋅1lb453.6g =20.82kJg Finally, we can calculate the fuel value of one serving The fuel value per serving =Total fuel value per gram⋅m =20.80kJg⋅42g =874.44kJ Result =874.44kJ
