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.
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.
3000 ml of water has a mass of 3 kg.
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
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.
The remaining water in Kia's bottle has a mass of about 500 grams.
A molecule of water has a mass of 18 amu.
Approximately 18.16 units

The mass of the water molecules is greater than the mass of the helium atoms. It just so happens I had the same question in science, and that's what I put down. It might be wrong, it might not. But I'd be at least at like 65-35% chance it's right.
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.
At 4 degrees C, 175 ml of pure water would have mass of 175 g.
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
The answer will depend on how much water - a drop, a cupful, a bucketful, a whole lakeful or WHAT!
