272cm³ of carbon (iv) oxide were collected over water of 150⁰c and 782mmHg pressure. Calculate the volume of the dry gas at s. t.p? (s. v.p. of water at 150⁰c is 12mmhg)

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
