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.

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.
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.
Why does glucose diffuse slower than water?
The glucose molecule is much larger than the water molecule.
How much bigger is an oleic acid molecule than a water molecule?

A person has a pumpkin that has a mass of 4.8 kilograms If 0.9 of its mass is water how much of its mass is water and how much of its mass is not water?
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
How much ocean water is in a molecule?
A molecule of water has a mass of 18 amu.
How much mass does a water molecule have?
Approximately 18.16 units
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 does the mass of an element tell you about a molecule?

What does the mass percent of an element tell you about molecule?
it tells you how much of the molecule the element is
What does mass percent of an element tell you about a molecule?
it tells you how much of the molecule the element is

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.
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 the mass per element tell you about a molecule?
These informations add knowledge about the chemical composition of a molecule and the molar mass.
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
