True
False
Answer: True
Step-by-step explanation:
The first step to caculating the total number of kilocalories in one serving of the yogurt is to know how many grams are water, carbohydrates, proteins, or lipids, based on the given porcentages.
Water: 170 x 0.76 = 129.2 g
Carbohydrate: 170 x 0.20 = 34g
Protein: 170 x 0.03 = 5.1g
Lipid: 170 x 0.001= 0.17g
The second step is to calculate their respective amount of kilocalories, considering that carbohydrates and proteins have 4 kilocalories per gram, and lipids have 9.
(129.2g x 0 kcals) + (34g x 4 kcals) + (5.1g x 4 kcals) + (0.17g x 9 kcals)
0 + 136 + 20.4 + 1.53 = 157.93 (158 round up)
