Determine the number of atoms of 25 g iron(II) chloride

3.56x10²³ atoms

Explanation:

To solve this question we need first to determine the moles of iron (II) chloride, FeCl₂, using its molar mass. Then, using Avogadro's number we can solve for the number of atoms:

Moles FeCl₂ - Molar mass: 126.751g/mol-

25g FeCl₂ * (1mol / 126.751g) = 0.1972 moles

Number of atoms:

1 mole of FeCl₂ are 6.022x10²³ molecules of FeCl₂, that means 0.1972moles are:

0.1972mol * (6.022x10²³ molecules / 1mol) = 1.188x10²³ molecules of FeCl₂

In 1 molecule of FeCl₂ there are 3 atoms (1 of Fe and 2 of Cl), in 1.188x10²³ molecules of FeCl₂ there are:

1.188x10²³ molecules of FeCl₂ * (3atoms / molecule) =

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
