Answer:

Dalton law of partial pressure states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of partial pressures of the individual gases.

If 3 substances be x,y,z

$\\ \tt\longmapsto P_{net}=P_x+P_y+P_z$

Where

$\\ \tt\longmapsto P_x=\dfrac{n_xRT}{V}$

$\\ \tt\longmapsto P_y=\dfrac{n_yRT}{V}$

$\\ \tt\longmapsto P_z=\dfrac{n_zRT}{V}$

P is partial pressure
n is number of moles
V is volume
T is temperature

A 225 g sample of french fries supplies 460 kilocalories of energy. 65% of those calories come from fat, which supplies 9 kiloca

brilliants [131]

The french fries gives 460 kilocalories and 65% of those calories come from fat. Then, calorie that comes from fat would be: 65% * 460 kcal= 299 kcal

Fat gives energy about 9kcal/gram. Then, the total mass of fat in the french fries would be: 299 kcal/ (9kcal/g)= 33.22 grams

Moles
Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Stoichiometry

Using Dimensional Analysis

Explanation:

Step 1: Define

Identify

[Given] 1.8 mol Mg

[Solve] atoms Mg

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[DA] Set up: $\displaystyle 1.8 \ mol \ Mg(\frac{6.022 \cdot 10^{23} \ atoms \ Mg}{1 \ mol \ Mg})$
[DA] Multiply [Cancel out units]: $\displaystyle 1.08396 \cdot 10^{24} \ atoms \ Mg$
