Question

How many atoms of boron are in 3.66 moles of boron?

Answer 1

I want you to evaluate....

...

if 1 Mol of boron =72×NA boron atoms what about 3.66 moles...
...

"you can equate that"

Answer 2

Answer: The number of atoms = 2.20×10^24

Step-by-step explanation:

From stoichiometry relations;

Mole =

Number of particles/ Avogadro's constanst

Particles may be atoms, molecules or ions

Avogadro's constant is the number of atoms in a mole = 6.02×10^23

3.66= Number of atoms /6.02×10^23

Number of atoms =3.66×6.02×10^23

Number of atoms =2.20×10^24

Therefore the number of atoms present is

2.20×10^24
