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

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

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
