PLEASE HELP!!!!! WILL GIVE BRAINLIEST!!!!

so 2.46 X 10^28 contains (2.46 X 10^28)/(6.02 X 10^23) =

(2.46 X 10 X 10^27)/ (6.02 x(10^23) = (24.6/6.02) X 10^ (27-23)=

4.09 X 10^4 = 40,900

Answer:

4.09 X 10^4 = 40,900 moles

Explanation:

How many moles of Magnesium(Mg) are

in 2.46 x 10^28 atoms of Magnesium?

PLEASE LEARN THIS FUNDAMENTAL RULE OF CHEMISTRY...1 MOLE OF ANYTHING CONTAINS AVOGADROS NUMBER OF PARTICLES}

6.02 X 10^23.09

so 2.46 X 10^28 contains in moles(2.46 X 10^28)/(6.02 X 10^23) =

(2.46 X 10 X 10^27)/ (6.02 x(10^23) = (24.6/6.02) X 10^ (27-23)=

4.09 X 10^4 = 40,900 moles

Taking into account the definition of dilution,  the new concentration of the solution is 0.2567 M.

First of all, you have to know that   dilution is the reduction in concentration of a chemical in a solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volumeof the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:

0.385 M× 0.600 L= Cf× 0.900 L

Solving:

Cf= (0.385 M× 0.600 L)÷ 0.900 L

Cf= 0.2567 M

In summary, the new concentration of the solution is 0.2567 M.

Since Ghs. 421.78 was deducted from Adjoa's salary pay, her take home pay is Ghs. 4265.46.

Given the following data:

Gross profit can be defined as the profit earned by a business after subtracting its cost of manufacturing and distributing goods from its total revenue (sales).

On a related note, gross salary is the amount of money earned by an individual before any deduction such as tax.

To find how much take home pay Adjoa earned this past month:

[tex]Take\;home = Gross\;salary - deduction\\\\Take\;home = 4687.24 - 421.78[/tex]

When 100 photons of light pass through a sample and 64 photons are detected after the passage of light, the number of photons transmitted through the sample is 64.

This is based on the methods of calculating the absorbance of light, which is depicted as the higher the amount of light transmission, the lower the amount of light absorbed.

Thus, when 64 photons of light in 100 photons are detected, 64 photons are transmitted, and therefore, the number of photons absorbed is 36.

Hence, hypothetically, if 100 photons of light are transmitted, 0 photons of light will be absorbed.

Therefore, in this case, it is concluded that the correct answer is 64 photos.

Taking into account the definition of density and scientific notation, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.  That is, density is the relationship between the weight (mass) of a substance and the volume it occupies.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

In this case, you know that:

Replacing in the definition of density:

[tex]density=\frac{0.216 kg}{237 mL}[/tex]

Solving:

density= 0.000911 [tex]\frac{kg}{mL}[/tex]

On the other side, scientific notation is a quick way to represent a number using powers of base 10.  

The numbers are written as a product:

a×10ⁿ

where:

In this case, the density expressed in scientific notation is: 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

In summary, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

Answer:

methane

Explanation:

The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4). Natural gas also contains smaller amounts of natural gas liquids (NGL, which are also hydrocarbon gas liquids), and nonhydrocarbon gases, such as carbon dioxide and water vapor.The main component in natural gas is methane. It also has ethane, propane, butane, hydrocarbons.
