Molecular Force Comparison
What is the strongest molecular force that could occur between two molecules of each below?
The strongest molecular force that could occur between two molecules is as follows:
Hydrogen molecule (H2): Dipole-dipole interaction
Oxygen molecule (O2): London Dispersion Forces
Nitrogen molecule (N2): London Dispersion Forces
Carbon dioxide (CO2): Dipole-dipole interaction
Water (H2O): Hydrogen bonding
Note: London Dispersion Forces are the weak attractive forces that occur between all molecules due to the fluctuation of their electron clouds. Dipole-dipole interactions are attractive forces between molecules that have a permanent dipole moment. Hydrogen bonding is a stronger attractive interaction that occurs between a hydrogen atom covalently bonded to a highly electronegative atom and another highly electronegative atom.

The short answer is: 60.05 g/mol. Water, in comparison, has a molecular weight of approximately 18 g/mol. Please note, there is a difference between "molecular mass" and "molar mass." Molar mass is typically used when describing bulk properties. Molecular mass is often reserved to describe molecules. G/mol is molar mass. More information on how molecular weights are calculated can be found at the link below.

Though there are some other applications of the term molecular machine, it is primarily used in the field of nanotechnology. In the world of the ultra small, it is used to mean a handful of molecules (and sometimes a big handful) that perform a function or do work. You can read a bit more by using the link below. It will take you to the Wikipedia post on the molecular machine.
Molecules are not alive, However: 1. All matter is composed of tiny particles called molecules. 2. There are spaces between molecules. 3. Molecules are constantly moving. 4. Molecules attract one another. see link below for more details.
The term average must be used as the molecular motion is not completely uniform. ie. some of the molecules will vibrate at different frequencies and amplitudes, around a fixed average position. This is shown as water can evaporate even if it is below the boiling point, as some molecules have enough energy to escape. the boiling point is when the average energy is 100 degrees centigrade, so the molecules turn to gas.
Atoms bond together by sharing or transferring valence (outer shell) electrons, either in covalent (molecular) bonds or in ionic bonds.See related questions below.
