The cool thing about atomic masses listed on the Periodic Table is not only does it represent how many grams are in one mole of that element, but also how many amu (Atomic Mass unit)s one atom weighs. So, you can just add 2H + O = (2*1.00794) + (15.9994) = 18.0153 g/mol = 18.01528 amu. Then, you can use the conversion factor 1 amu = 1.66053886*10-24 grams to find the mass of one molecule: 2.99151058*10-23 grams.
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.
These informations add knowledge about the chemical composition of a molecule and the molar mass.
The glucose molecule is much larger than the water molecule.

The pumpkin's mass is 4.8 kg, and 0.9 of its mass is water. This means 0.1 of its mass is not water. To find the mass of water: 4.8 kg x 0.9 = 4.32 kg of water To find the mass of not water: 4.8 kg - 4.32 kg = 0.48 kg of not water
A molecule of water has a mass of 18 amu.
Approximately 18.16 units
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.

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.

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
