Answer:

<h3>The answer is 1.53 moles</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}  \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{9.2 \times  {10}^{23} }{6.02 \times  {10}^{23} }  \\  = 1.52823920...

We have the final answer as

<h3>1.53 moles </h3>

Hope this helps you

Energy of motion or change in position
Sholpan [36]
<span>Kinetic energy is the energy at move or at motion. The kinetic energy of objects depend on its mass (m) and its </span>velocity (v)<span>. The mass of an object can be measured in kilograms while its mass can be measured in meters per second. The objects' energy at motion is very dependent to its mass and velocity therefore, the formula in finding the kinetic energy of an object is </span>

K = 1/2 x mass (m) x velocity (m/s)2

<span>On the other hand, the kinetic energy of atoms and molecules are measured differently. It is measured through temperature.<span>

[HELP PLEASE]How is electronegativity related to covalent bonding and molecular polarity?
Anuta_ua [19.1K]

Answer:

The larger the value of the electronegativity, the greater the atom's strength to attract a bonding pair of electrons. ... Electronegativities give information about what will happen to the bonding pair of electrons when two atoms bond. A bond in which the electron pair is equally shared is called a nonpolar covalent bond.
