 Fat: 1 gram = 9 calories    Protein: 1 gram = 4 calories    Carbohydrates: 1 gram = 4 calories    Alcohol: 1 gram = 7 calories"
So, (12 g carbohydrates)*4 Cal=48 Cal; (9 g fat) *9 Cal=81 Cal; (9 g protein)*4 Cal=36 Cal
48 Cal + 81 Cal + 36 Cal = 165 Cal in one glass of milk

Answer:

165Kcal in a cup of whole milk

Explanation:

Hello! Let's solve this!

We know that 1g

carbohydrate = 4 Kcal

1g protein = 4Kcal

1g fat = 9Kcal

We do the conversion of each one

carbohydrates = 12g * 4Kcal * g = 48Kcal

Proteins = 9g * 4Kcal / g = 36Kcal

fat = 9g * 9Kcal / g = 81Kcal

We add all the results to have the total Kcal

48Kcal + 36Kcal + 81Kcal = 165Kcal in a cup of whole milk

<u>Stoichiometry</u>

  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

4.93 × 10²³ atoms Ag

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

  1. Set up:                              \displaystyle 4.93 \cdot 10^{23} \ atoms \ Ag(\frac{1 \ mol \ Ag}{6.022 \cdot 10^{23} \ atoms \ Ag})
  2. Divide:                              \displaystyle 0.818665 \ mol \ Ag

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

0.818665 mol Ag ≈ 0.819 mol Ag

Water is composed of the same elements as hydrogen peroxide why do these substances have different properties
Dmitrij [34]
They have different ratios of elements. Water is H20 and Hydrogen Peroxide is H202. The extra oxygen atom in hydrogen peroxide causes it to be structured and react differently.

The atomic mass of Aluminum is 26.98154 g/mol. Is it possible to have 5.0*10-25g of Al
suter [353]
I believe the correct answer is no, it is impossible to have 5.0*10^-25g of Al. One atom of Al weighs <span>4.48*10^-23 g/atom Al which means</span> it is impossible to have any weight of Al less than that. Hope this answers the question. Have a nice day.
