Hey there!

There are 6.022 x 10²³ particles in 1 mole.

We have 3.55 moles.

6.022 x 10²³ x 3.55

2.14 x 10²⁴

This is how many particles we have.

NaCl has 2 atoms for every unit.

So we multiply this by 2.

2 x 2.14 x 10²⁴ = 4.28 x 10²⁴

There are 4.28 x 10²⁴ atoms in 3.55 moles of sodium chloride.

Hope this helps!

Answer:

We know that 1 mole of anything contains an Avogadro's number of atoms or 6.023 x 10^23 atoms. Thus, 1 mole of NaCl will contain 6.023 x 10^23 atoms each of Na and Cl, or a total of 12.046 x 10^23 atoms. NaCl is an ionic compound formed by the loss of one electron from Na and the gain of the one electron by Cl.

<h3>What is hexadecimal system?</h3>

Hexadecimal is an easy route for addressing twofold. It is vital to take note of that PCs don't utilize hexadecimal - it is utilized by people to abbreviate parallel to an all the more effectively reasonable structure. Hexadecimal Number System is generally utilized in Computer programming and Microprocessors. It is likewise useful to portray colors on pages. Every one of the three essential tones is addressed by two hexadecimal digits to make 255 potential qualities, hence bringing about in excess of 16 million potential tones. The primary benefit of utilizing Hexadecimal numbers is that it utilizes less memory to store more numbers, for instance it stores 256 numbers in two digits while decimal number stores 100 numbers in two digits. This number framework is likewise used to address Computer memory addresses.

Answer:

A. how cholesterol works in the body.

Explanation:

If we know the precise structure of a molecule (by X-ray crystallography), we can understand more about how it interacts with cells, proteins, and other molecules. It can also tell us what reactions it might take part in.

Therefore, we can learn more about how it works in the body and what activities it takes part in in the cells of the body.

what is the theoretical mass of xenon tetrafluoride that should form when 130.g of xenon is reacted with 100.g of F2? what is th
serg [7]

Answer:

The answer to your question is: 70.7 %

Explanation:

Equation

                  Xe   +   2F₂    ⇒    XeF₄

limiting reactant = Xe

Xe is the limiting reactant because the ratio is:

theoretical = 131/ 76 = 1.72 g

experimental ratio = 130/100 = 1.3  the amount of F increased.

                     131.3 g of Xe ------------------ 207 g of XeF₄

                     130 g of Xe  -------------------  x

                         x = (130 x 207) / 131.3

                        x = 205 g of XeF₄

% yield = 145 / 205 x 100

% yield = 70.7
