Calculate the moles of FeFe in 1.17×10221.17×1022atoms of FeFe.

Express the number of moles numericall

The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles

Explanation:

Step 1: Data given

Number of atoms of Fe = 1.17 * 10^22 atoms

Number of Avogadro = 6.022 *10^23

Step 2: Calculate number of moles Fe

Moles Fe = atoms Fe / number of Avogadro

Moles Fe = 1.17*10^22 atoms / 6.022*10^23 / moles

Moles Fe = 0.0194 moles

The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles

first one is the correct answer

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
