How much ocean water is in a molecule?

A molecule of water has a mass of 18 amu.


The mass of a single TNT molecule?

The molar mass of TNT (Trinitrotoluene) is approximately 227.1 g/mol. This means that a single TNT molecule would have a mass of 227.1 g/mol (or 2.38 x 10^-22 grams per molecule).


What you the mass number of H2o?

The mass number of water (H2O) is calculated by summing the atomic masses of its components. Hydrogen has an atomic mass of 1 and oxygen has an atomic mass of 16. Therefore, the mass number of water is 18.


Can you boil a single molecule of water?

no


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 the mass of hydrogen molecule is greater then the mass of hydrogen atom?

The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.


Grams of a single water molecule?

A single water molecule has a mass of about 18 grams per mole. This value is calculated from the atomic masses of two hydrogen atoms (each with an atomic mass of approximately 1) and one oxygen atom (with an atomic mass of around 16).


Does water have mass?

Yes, water has mass. All matter, of which water is one kind, has mass.


What is the Mass of a sulfur trioxide molecule?

The molar mass of sulfur trioxide (SO3) is approximately 80.07 grams per mole. This means that a single sulfur trioxide molecule has a mass of about 80.07 atomic mass units.


What is the smallest amount of water you can have?

A single molecule. If you split that up, it will no longer be water.


How much mass does a water molecule have?

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.
