State the difference between mass and weight

Mass is the measurement of what amount of matter is contained in an object. Whereas

weight is the measurement the pull of gravity on an object.

Another way to differentiate both is Mass is measured on a balance comparing a known amount a matter of to an unknown amount of matter and weight is measured on a scale.

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.
