Chemistry
1 answer:
Naya [18.7K]3 years ago
3 0

Answer:

<h3>The answer is 7.23 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{4.35 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 7.225913...

We have the final answer as

<h3>7.23 moles</h3>

Hope this helps you

Which of these compounds is most likely to be ionic? select one:
Vlada [557]
The compound that is most likely to be ionic is BaCl2
Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, thus they become cations and have a net positive charge. Non metals tend to gain electrons, forming anions that have a net negative charge.

Materials in Earth's interior?
Alina [70]

Answer:

The inner core is the Earth's "interior".

P-waves pass through both the mantle and core, but are slowed and refracted at the mantle / core boundary. Whereas, S-waves pass from the mantle to the core and are absorbed due to shear waves being incapable of transmitting through liquids. Therefore, this is (further) proof the outer core does not behave like a solid substance.
