If the sand is totally silicon dioxide and is assumed to be a uniform volume of one cubic millimeter then the number would be approximately 2*10^19 molecules, or 20,000,000,000,000,000,000
A molecule of of water contain 3 atoms.
There are 4 atoms of hydrogen in 2H2O.
Water is chemically H2O and there is no helium (He) in water. Water has two hydrogen atoms and one oxygen atom.
A grain of dust typically contains around 1 trillion (1,000,000,000,000) atoms. Dust particles vary in size and composition, leading to different numbers of atoms in each particle.

It depends on how much water you have!
there are 2 atoms of hydrogen in water
A molecule of of water contain 3 atoms.
There are two hydrogen atoms in one molecule of water (H2O).
H2OCount two atoms hydrogen in one molecule of water.
No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
