What is the molar mass of fluorine, f2? 9.00 g/mol 18.00 g/mol 19.00 g/mol 38.00 g/mol

Answer is: the molar mass of fluorine is 38.00 g/mol.

M(F₂) = 2 · Ar(F) · g/mol.

M(F₂) = 2 · 19.00 · g/mol.

M(F₂) = 38.00 g/mol.

Molar mass M represent the mass of a substance (in this example molecule of florine) divided by the amount of substance.

Ar is the atomic weight of a chemical element (in this example fluorine).

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
