1 mole H2O = 18.015g H2O = 6.022 x 1023 molecules H2O
1.5 x 1023 molecules H2O x 18.015g H2O/6.022 x 1023 molecules H2O = 4.5g H2O

What is the largest mass in amu that a water molecule could have using other isotopes?
The molecule T218O has molar mass of 24,031 g.
What the mass percent composition of an element in 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
How much does one water molecule weight?
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 the mass percent composition of an element in 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
Does a molecule have mass?
Yes. For example water molecules (2 hydrogen connected to 1 oxygen atom) have a bent shape.
How much ocean water is in a molecule?
A molecule of water has a mass of 18 amu.
What is the largest mass in amu that a water molecule could have using other isotopes?
The molecule T218O has molar mass of 24,031 g.
What is the mass of a water molecule in atomic mass units?
A normal water molecule weighs roughly 18 Amu's, so one mole of water weighs 18 grams. -KRogersaurus
How much mass does a water molecule have?
Approximately 18.16 units
What percent of mass of water molecule is hydrogen?
2 out of 18 or 11.1111 %

What is a molar mass of a molecule?
The molar mass of a molecule is the sum of atomic weights of the elements contained in this molecule.
A molecule of water is composed of two atoms of hydrogen and one atom of oxygen if the atomic mass number of hydrogen is 1 and the molecular mass of water is 18 the atomic mass of oxygen must be?
16
What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
Does a molecule have mass?
Yes. For example water molecules (2 hydrogen connected to 1 oxygen atom) have a bent shape.
