Molar mass of iron(III) oxide is 160g/mol

 160g ----------- of iron(III) oxide is ---------------- 6.02*10²³molecules
 79g   ----------- of iron(III) oxide is ---------------- x

x = [6.02*10²³*79g]/160g ≈ <u>2.97*10²³ molecules</u>

What is the strongest type of intermolecular force between solute and solvent in each solution?
Dvinal [7]

London Dispersion Force between solute and solvent in each solution is the strongest type of intermolecular force.

<h3>What is London Depression Force ?</h3>

There are 4 types of intermolecular forces -

  • Dispersion Force
  • Dipole–Dipole
  • Hydrogen Bonding, and
  • Ion-Dipole.

The London dispersion force is a transient attractive attraction that occurs when two nearby atoms' electrons occupy locations that cause the atoms to form temporary dipoles. This force is also known as induced dipole-induced dipole attraction.

Example ; If these atoms or molecules come into contact with each other, dispersion forces exist between them. Consider the London dispersion forces between two chlorine molecules. Both chlorine atoms are connected in this case via a covalent connection formed by the equal sharing of valence electrons between two chlorine atoms.

Thus from the above solution we can say that in between these solutions London Depression force is the strongest force.
