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.
You calculate it by using Avogadro's number: 6.022 x10 23 which is one mole of substance.
1.00 x 1024 divided by 6.022 x 1023 = 10 divided by 6.022 = 1.661 mol H2O
Use the molar mass of water (18.02 g mol-1) to get to the mass in grams.
18.02 g x 1.661 mol = 29.93 g H2O
1 molecule of water is the smallest thing water can be physically broken down to without changing its chemical formula... It consists of one oxygen and two hydrogen molecules. It weighs 18/(6.02 * 10^22) g
Since 6.02 x 1023 molecules is a mole, 1.00 x 1024 would be 1.66 moles.
Water has the mass of: (1.00794 g/mol x 2) + 15.994 g/mol = 18.009 g/mol
1.66 mol x 18.009 g/mol = 29.92 g
The molecule would normally have an atomic weight of 17, unless there were isotopes in the molecule.
A water molecule is made of two hydrogen atoms attached to an oxygen atom. Their atomic masses are 1 and 16 respectively. So the molecular mass of water is 2x1+16=18 grams per mole.
18 atomic mass unit or 18 gms
The density of ice is 0.9167 g/cm³ (cm³=ml) at 0°C at tmospheric pressure. Thus, 1kg of ice contains 1.091 Litre of water. Answer by TCY.
Because the electron, in effect has no (or very little atomic) mass and is travelling at near light speed, while the molecule of water (H20) has a relatively large atomic mass and is traveling at a much lower velocity (5 to 10 meters per second). This of course, as postulated in the question, relates only to gravitational affect and neglects drag caused by air resistence.
A liter of water has a mass of about one kg.
The generally accepted mass of water is 1kg per litre, so 54 litres would weigh in at 54kg
when you add pressure to a molecule it increases because pressure is like gas and when there is to much gas it has to expand.
A molecule of water has a mass of 18 amu.
Approximately 18.16 units

If a quarter of the mass of the molecule is iron and the mass of the molecule is 89600u, then the mass of iron is 22400u ... a quarter of the total mass.
These informations add knowledge about the chemical composition of a molecule and the molar mass.
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
At 4 degrees C, 175 ml of pure water would have mass of 175 g.

Bonded hydrogenially, but with much surface tension.
