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
One molecule of water has a mass of about 18 atomic mass units (amu), consisting of two hydrogen atoms and one oxygen atom. This translates to approximately 2.99 x 10^-26 kilograms.
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.

How much water is in a 1kg of ice?
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.
3000ml of water has a mass of how much kgs?
3000 ml of water has a mass of 3 kg.
Does water vapour have mass?
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.
Why does not the electron in a beam from an electron gun falls as much under gravity as a water molecule in a stream from a hose?
The electron has much less mass compared to a water molecule, which results in a significantly weaker gravitational force acting on it. Additionally, the electron's high velocity in the beam can counteract the gravitational force, allowing it to travel in a straight path rather than falling due to gravity.
How much mass does Kia's remaining water have?
The remaining water in Kia's bottle has a mass of about 500 grams.

If the mass of water is 4.5 times greater than the mass of helium how does the mass of a water molecule compare with the mass of a helium atom?
The mass of a water molecule (H2O) is significantly greater than the mass of a helium atom. A water molecule consists of two hydrogen atoms and one oxygen atom, making it much heavier compared to a single helium atom.
How much iron will be present in one molecule of hemoglobin if hemoglobin has 0.25 percent by mass iron and the molecular mass of hemoglobin is 89600u?
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.
What does the mass per element tell you about a molecule?
These informations add knowledge about the chemical composition of a molecule and the molar mass.
How much mass would 175ml of water have?
At 4 degrees C, 175 ml of pure water would have mass of 175 g.
What does percent composition tell you about a molecule?
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
