there are 2 atoms of hydrogen in water
It depends on how many molecules of HCl you have. In one molecule of HCl there are 2 atoms present.
In a dozen molecules of H2O, there are 24 atoms of hydrogen because each H2O molecule contains two hydrogen atoms.
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
A molecule of fructose contains 6 carbon atoms, 6 oxygen atoms, and 12 hydrogen atoms.
Water molecules are H2O so there are 2 Hydrogens bonded to 1 oxygen.
The molecule contains two hydrogen-bond donors.
The number of hydrogen atoms of present in a hydrogen molecule are 2.

Each molecule of ammonia has three hydrogen atoms; therefore, 26 molecules of ammonia contain 26 X 3 = 78. However, these hydrogen atoms do not constitute hydrogen molecules, so the literally correct answer is zero.
A molecule can have a variable number of elements. For example, the simplest molecule, hydrogen gas (H2), contains two hydrogen atoms. More complex molecules, such as glucose (C6H12O6), contain multiple elements such as carbon, hydrogen, and oxygen.
there are 2 atoms of hydrogen in water
H2O consists of two Hydrogen and one Oxygen. Three sets of these would mean 9 atoms in your three molecules of water.
