how many hydrogen atoms are present in the water?
533483
The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part.
464328
There are 2 hydrogen atoms in 1 molecule of water. 1 mole of H2O contains 2 moles of H, and each mole of H contains 6.02x10^23 atoms of H.
1438072
For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom.
107893
Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
909163
of molecules is 20* 6.022* 10^ 23. One molecules of water contains 3 atoms. So in total, number of atoms = 3*20*6.022*10^23.
280678
Water consists of 2 hydrogen atoms and 1 oxygen atom. Each hydrogen atom has 1 proton, no neutrons (assume all H are protonium) and 1 electron. The oxygen atom has 8 protons, 8 neutrons (most abundant isotope) and 8 electrons.
354676
1 mole of hydrogen gas contains 6. 02×1023 atoms. 1 molecule of hydrogen(H2) contains two atoms of hydrogen.
1217188
0.05 grams of water contains= 6.02*10^23*0.05/18= 1.67*10^21 molecules. (ans.) 2. 1 molecule of water contains= 2 atoms of hydrogen.
111279
A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. Sulfuric acid has the chemical formula H2SO4.
118164
( 1/4 of a mole) x (6.02 x 1023 atoms/mole) = approximately 1.5 x 1023 atoms. If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

Answer. Total number of Hydrogen atoms = 0.12 × Avagadro no.
895944
There is one atom of oxygen, and two atoms of hydrogen in each water molecule, each molecule of water contains three atoms, making the formula H2O.
1108324
Water is H2O so 5 Moles of water contains; 2 x 5 x 6.022140857 × 10^23 atoms of Hydrogen ! There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole.
164218
A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets. The atoms consist of matter that has a nucleus in the centre.
545782
Answer and Explanation: A water molecule can form four hydrogen bonds. Water is made up of two hydrogen atoms and an oxygen atom.

These atoms have the same number of protons, but slightly different number of neutrons. How convenient! Looks like you have 2 moles of Water! So there are 4 moles of Hydrogen, and 2 moles of Oxygen in 2 moles of Water.

Part 1. There are 4 moles of hydrogen atoms in 36 grams of water, which is choice a.
