The number of moles of silver, Ag, that are in 7.54 × 10²³ atoms of silver is 1.25 moles

From the question,

We are to determine the number of moles of silver, Ag, that are present in 7.54 × 10²³ atoms of silver

From the formula

[tex]Number\ of\ moles =\frac{Number\ of\ atoms}{Avogadro's\ constant}[/tex]

Avogadro's  constant = 6.022 × 10²³  atoms mol⁻¹

and

From the given information

Number of silver atoms = 7.54 × 10²³ atoms

Putting the parameters into the formula, we get

Number of moles of silver present = [tex]\frac{7.54\times 10^{23} }{6.022\times 10^{23}}[/tex]

Number of moles of silver present = 1.2520757 moles

Number of moles of silver present ≅ 1.25 moles

Hence, the number of moles of silver, Ag, that are in 7.54 × 10²³ atoms of silver is 1.25 moles

Answer:

0.00000000000000084

Explanation:

The phenomena which  wind causes  are waves and surface currents.

Surface currents are caused by  winds  which blow over the ocean water and result in creation of waves. Surface currents  are horizontal streams of water which are capable of  flowing thousands of kilometers and can reach great depths.

Surface currents play a major role in determining the climate all over the world. They are influenced by three major factors 1) overall global wind patterns 2)rotation of earth 3)shape of ocean basins . When a surface  current collides with the land it  changes the direction of currents.

Because of surface currents the global climate has warmer water  from equator to the cooler parts of the ocean  as they transfer heat energy.

The quantity of β-hydroxybutyrate the bear can produce

during hibernation is 3,073.30grams.

Hibernation is defined as the period of less activity by animals to conserve energy to survive coarse weather conditions.

A typical example of an animal that hibernates is the bear.

From the question, a bear is able to accumulate 25kg (25000grams) of triglyceride.

To calculate quantity of β-hydroxybutyrate that would be produced from 25kg triglyceride;

846g of triglyceride = 104grams of β-hydroxybutyrate

25000g of triglyceride = x grams

(Cross multiple to solve for x grams)

X = 104 × 25000/846

[tex]x = \frac{104 \times 25000}{846} [/tex]

[tex]x = \frac{2600000}{846} [/tex]

[tex]x = 3073.30grams[/tex]

Therefore, the quantity of β-hydroxybutyrate the bear can produce during hibernation is 3,073.30grams.

Answer:

In the final solution, the concentration of sucrose is 0.126 M

Explanation:

The number of moles of solute in the volume taken from the more concentrated solution will be equal to the number of moles of solute in the diluted solution. Then, the concentration of the first solution can be calculated using the following equation:

Ci · Vi = Cf · Vf

Where:

Ci = concentration of the original solution

Vi = volume of the solution taken to prepare the more diluted solution.

Cf = concentration of the more diluted solution.

Vf = volume of the more diluted solution.

For the first dillution:

26.6 ml · 2.50 M = 50.0 ml · Cf

Cf = 26.6 ml · 2.50 M / 50.0 ml

Cf = 1.33 M

For the second dilution:

16.0 ml · 1.33 M = 45.0 ml · Cf

Cf = 16.0 ml · 1.33 M / 45.0 ml

Cf = 0.473 M

For the third dilution:

20.0 ml · 0.473 M = 75.0 ml · Cf

Cf = 20.0 ml · 0.473 M / 75.0 ml

Cf = 0.126 M

In the final solution, the concentration of sucrose is 0.126 M

How many moles is 7.78 x 1024

formula units of MgCl2?

answer: 7966.72

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, there are 0.49moles of  MgCl[tex]_2[/tex] in  7.78 x 10²⁴atoms of MgCl[tex]_2[/tex] .

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample. There are so many formula for calculating mole.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of MgCl[tex]_2[/tex]= 7.78 x 10²⁴

Substituting the values

mole= 7.78 x 10²⁴÷ 6.022×10²³

mole = 0.49moles of  MgCl[tex]_2[/tex]

So, there are 0.49moles of MgCl[tex]_2[/tex] in  7.78 x 10²⁴atoms of MgCl[tex]_2[/tex] .

Answer:

Explanation: i just finished this chapter of the class

Answer:

1). Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.

2) In contrast, the number of neutrons for a given element can vary. Forms of the same atom that differ only in their number of neutrons are called isotopes.

3) Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
