Best Answer

The mass of any molecule is equal to the sum of the Atomic Mass Units of all of its constituent atoms. Atomic Mass Unit values may be found on any Periodic Table. In this case, a water molecule consists of two Hydrogen atoms and one Oxygen atom. Hydrogen has a mass of approximately 1 AMU. Oxygen has a mass of approximately 16 AMU. Therefore, the mass of one molecule of water is approximately 18 AMU (or 18.01528 AMU exactly). What does this number mean? If you had exactly 6.022 x 10^23 molecules of water, it would weigh 18 grams.

What is a single water molecule?

One single water molecule is....two hydrogen atoms bonded to one oxygen atom with molecular weight 18.016. You will never see one molecule of water as that is too small to view without special equipment.


Is liquid oxygen heavier than water?

A thing's heaviness is a measure of gravity's effect on its mass. Molecule for molecule, H2O (water) is heavier than O2 (oxygen); however, you are comparing two different molecules at two different pressures and densities. Oxygen, while lighter than water (molecule for molecule) at normal pressures, is much heavier when compressed to the point of condensation. Liquid oxygen has a weight of 1.141 g/ml, whereas water's weight is 1 g/ml. They are very close to the same weight, but liquid oxygen is almost 15% heavier.


How much indidvidual atom are in one molecule of water?

The formula of water is H2O, showing that each molecule contains one oxygen atom and two hydrogen atoms. Therefore, each molecule contains three atoms.


How many molecules of hydrogen does water contain?

A molecule of water contains two atoms of hydrogen. A molecule of hydrogen contains two hydrogen atoms. Therefore, one molecule of water contains one hydrogen molecule, but it is unusual to think in these terms. Check the wording of your question.


What type bond is responsible for holding one water molecule to another water molecule?

The intermolecular forces between water molecules are hydrogen bonds, a special (and much stronger) version of dipole-dipole bonds.

Does the molecules of mercury is heavier than molecule of water?

If you understand what molecular weight (MW or FW) means, then look at the molecular weight of one molecule of mercury (Hg2) and compare that to the molecular weight of an H2O molecule.Which is heavier?

HOW MUCH ENERGY IT TAKES TO ERASE ONE MOLECULE OF WATER ONE DEGREE?

A water molecule can be erased is the chemical bonds are destroyed. Although water is characterised as one oxygen atom attached to two hydrogen atoms, water molecules seldom exist in isolation: there are often clusters of four. This makes it much more difficult to calculate the amount of energy required to break the bonds and erase the water molecule from existence.
