In 3 molecules of H2O, which is 3H2O, there are 6 hydrogen atoms and 3 oxygen atoms. You multiply the coefficient of 3 times the subscript of each element. When there is no subscript, it is assumed to be 1.

Is helium only one type of atom?
There are two naturally occurring isotopes of helium: He-3 (which is very rare, comprising 0.00014% of naturally occurring helium), and He-4 (which comprises the other 99.99986%of naturally occurring helium). Whether helium is one type of atom or not then depends on the definition of "one type of atom"; if He-3 and He-4 are considered different types of atom due to their differing numbers of neutrons, then no, helium is not one type of atom; if He-3 and He-4 are both considered the same type of atom due to their common number of protons, then yes, helium is one type of atom.
How many atoms makes up each water molecule?
6 : 4 hydrogen 2 oxygen ------------------------------------ That would be for two water molecules as one is H20 - therefore 3 atoms
What the atomic number tell us?
The atomic number of an atom is the number of protons in the nucleus of an atom. The number of protons determines the identity of an element and its properties. Hope this helps :3
A Lithium atom has an atomic mass of 6 How many neutrons does this atom have?
This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
Can the number of moles of a substance be found by looking at a balanced equation?
yes the number of moles is the the number before the substance for example if the equation is balanced and you want to find H2O and it appears like 3H2O in the equation then their are 3 moles of H2O
What is the number of each type of atom in NaHCO3?
Sodium bicarbonate has: 1 sodium atom, 1 hydrogen atom, 1 carbon atom, 3 oxygen atoms.
What is the total number of atom in H2O?
The water molecule is made up of 2 atoms of Hydrogen and one atom of Oxygen. So a total of 3 atoms. For other measurements, google Avogadro, mols, etc.

What does 3 types of subscript tell you?
- the atomic number of a chemical element or- the number of a type of an atom in a molecule or- indices for physical/chemical parameters
How many atoms are needed to make 30000000000000000000 molecules of water?
There are 3 atoms in one molecule of water (H2O is two hydrogen atoms and one oxygen atom)... so just multiply the number of molecules by 3.
What number of protons in lithium?
Lithium has the atomic number of 3, which means it has 3 protons, and a neutral atom of lithium has 3 electrons.
What does an atom of lithium-7 have as an equal number?
In a neutral atom of lithium-7, the number of protons equals the number of electrons. The atomic number of lithium is 3, which is the number of protons. So a neutral atom of lithium-7 has 3 protons and 3 electrons.
How many electrons do an atom with an atomic number of 3?
if it is a netrual atom it will have 3 but if it is charged it will change
5. Which of the following represents a compound H H-3 H2O O-16?
HH3 would be a Hydrogen-1 (protium) atom bound to a Hydrogen-3 (tritium) atom - since both are just isotopes of hydrogen it doesn't qualify as a compound. By the same token, the oxygen would not be a compound H2O is water - with 2 different elements it qualifies as a compound.
How many protons does linthium have?
An atom's atomic number tells us its number of protons. Lithium's atomic number is 3. Thus lithium has 3 protons per atom.
How many atoms are in 2.25 mol of water?
The number of molecules is 15,055 352 142 5.10e23.
Will H2O come back on tv?
H2o is on tv episode 1 and 2 episode 3 should come soon but episode 4 is if number 3 is succsesful
