Pl help !! what are the steps to convert from atoms, compounds, formula units, ect to moles

Explained below.

Explanation:

From avogadro's number, we know that;

1 mole = 6.022 × 10^(23) atoms, molecules, protons e.t.c.

Now,to convert from atoms, compounds, formula units, etc to moles, what we will do is just to divide the amount of the particle value given in the specific units by avogadro's number.

For example, to convert 23 × 10^(20) atoms to moles, we will have;

Number of moles = (23 × 10^(20))/(6.022 × 10^(23)) moles = 0.00382 moles

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
