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 largest mass of a water molecule (H2O) using other isotopes would be if both hydrogen atoms were deuterium (2H) isotopes instead of normal hydrogen (1H) isotopes. In this case, the total mass of the water molecule would be 20 amu, as each deuterium atom has a mass of 2 amu and the oxygen atom has a mass of 16 amu.
Does a molecule have mass?
Yes. For example water molecules (2 hydrogen connected to 1 oxygen atom) have a bent shape.
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
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.

How much ocean water is in a molecule?
A molecule of water has a mass of 18 amu.
Does water have mass?
Yes, water has mass. All matter, of which water is one kind, has mass.
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 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

What is the reduced mass of water?
The reduced mass of water is approximately 8.3 × 10^-27 kg. This value is calculated to account for the relative motion of the atoms in the water molecule which affects its overall mass.
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 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.
Why does a heavy water molecule have more mass than a normal water molecule?
Heavy water is formed from an isotope of Hydrogen called Deuterium which is 1 proton and 1 neutron whereas a normal hydrogen atom is only 1 proton. The extra particle causes the atom to have more mass and causes it's density to be greater than that of water
