In the world of chemistry a mole is a number of something a very large number of something.Just as a dozen is 12 of something a mole is about 6.02*10^23 of something.
In chemistry we like the number of atoms or molecules in moles.
If one mole is equal to 6.02*10^23 atoms and you have 9.00 *10^23 atoms then how many moles do you have?

Answers

Answer;

= 1.495 moles

Explanation;

-One mole contains 6.02 ×10^23 particles

Therefore;

1 mole = 6.02 ×10^23 atoms

Thus; 9.00 ×10^23 atoms will have;

= 9.00 ×10^23 atoms / 6.02 ×10^23 atoms

= 1.495 moles

Answer:

2.49

⋅

−

moles Pb

Explanation:

Before doing any calculations, it's worth noting that atoms do not contain moles, it's the other way around.

A mole is simply a collection of atoms. More specifically, you need to have exactly

6.022

⋅

atoms of an element in order to have one mole of that element - this is known as Avogadro's number.

In your case, you must determine how many moles of lead would contain

1.50

⋅

atoms of lead.

Well, if you know that one mole of lead must contain

6.022

⋅

atoms of lead, it follows that you get

1.50

⋅

atoms of lead in

1.50

⋅

atoms of Pb

⋅

1 mole Pb

6.022

⋅

atoms of Pb

2.49

The isotope atoms differ in ?

Answers

An isotope is formed basically when the amount of neutrons are different than the amount of protons in the nucleus. Therefore, we'd get a variation in the atomic mass (number of neutrons and protons). This is what makes isotopes different.

So, the answer would be: Isotope atoms differ in neutrons.
