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

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

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

I want you to evaluate ...

...

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

...

"you can equate that"
