If you think to molar mass, the value is 18 g.
For example - dihydrogen oxide.
51.2 g H20
2 H2O is the chemical formula of two molecules of water, not a reaction.
Mass = weight /gravity Density = Mass / Volume So, if you know the density and the volume, you can calculate the mass. Also, you can measure the mass by measuring the weight. On earth, mass and weight are equal.
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
the scientific formula is H2O

Not sure on formula but do you mean H20?
It is h20 and citric acid
18.02 AMU.

H20 is a formula for water. The substance has 2 hydrogen molecules to every 1 oxygen molecule.
In the chemistry formula, H2O, the "H" stands for hydrogen. The "O" stands for oxygen.
