Answer:
1.54×10^20 atoms
Explanation:
It's done by using the relation
N=n×L where,
N = number of entities present
n= amount of substance (mole)
L= Avogadro's constant which is 6.02×10^23
now from the question, given
n=0.000256
And L=6.02×10^23
N= 0.000256×6.02×10^23
N= 1.54×10^20 atoms

Answer:</h3>
156 calories
<h3>
Explanation:</h3>
- Carbohydrates, proteins and fats are food substances used by living organisms to generate energy required for the day to day activities.
- They supply energy which differs per gram for each food substance.
- That is;
1 g of carbohydrate = 4 calories
1 g of fat = 9 calories
1 g of protein = 4 calories
Therefore, whole milk serving containing 8.0 g of fat, 8.0 g of protein and 13 g of carbohydrates will contain the following number of calories;
8.0 g of fat = 8 g × 9 cal/g = 72 calories
8.0 g of protein = 8 g × 4 cal/g = 32 calories
13 g of carbohydrates = 13 g × 4 cal/g = 52 calories
Total amount of energy = 156 calories
Therefore, an 8 oz serving of whole milk contains 156 calories
