3 Atoms:
H2 is 2 atoms, since the subscript is a 2;
O is obviously singular.
2 + 1 = 3.
Coefficients, however, are different. You cannot change the subscript without changing the type of molecule (O is oxygen, which doesn't exist all by itself, O2 is in the air you breathe, and O3 is ozone) but coefficients can be changed because they only affect the amount of the molecules you have.

What is the total number of atoms in this formula H2O?
i think it's 6 moles of Hydrogen and 3 moles of oxygen. give the complete reaction to understand better.
How many atoms of hydrogen are there in the mole of H2O molecules?
In one mole of water (H2O), there are 2 moles of hydrogen atoms (H) due to the formula H2O having 2 hydrogen atoms. Since 1 mole of hydrogen contains Avogadro's number of atoms (6.022 x 10^23), in a mole of water there are 2 times Avogadro's number of hydrogen atoms, which equals 1.2044 x 10^24 atoms.
How many hydrogen atoms are in 301grams of H2O?
To determine how many hydrogen atoms are in 301 grams of H2O, we need to consider the molar mass of water (H2O). The molar mass of water is approximately 18 grams/mole. Since the molecular formula of water is H2O, it contains 2 hydrogen atoms. Using this information, we can calculate the number of moles in 301 grams of water and then determine the number of hydrogen atoms present.
How many hydrogen atoms are in 360 grams of water?
There are 4.8 x 10^24 hydrogen atoms in 360 grams of water. This is calculated by using Avogadro's number to convert the mass of water to moles, and then using the chemical formula of water (H2O) to determine the number of hydrogen atoms present in 1 mole of water.
What is the oxidation number of H2O?
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-

What does the number two mean in waters formula H2O?
Two hydrogen atoms.
What is the number of molecules in 16.75gbof h2o?
Approx 5.6*10^23 atoms.
How many atoms of hydrogen are there in the mole of H2O molecules?

What is the number and type of atom in 3 H2O?
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.

How many atoms are in 2.25 mol of water?
The number of molecules is 15,055 352 142 5.10e23.
When writing the formula for H2O do you use prefixes?
No. H2O speaks for itself. (It does not need any modifiers.)
What is the ratio of hydrogen atoms to oxygen atoms to be in a molecule of ice?
The ratio of the number of hydrogen atoms to the number of oxygen atoms in any physical state of water is always 2:1, as shown by the chemical formula of water, H2O.
How many atoms are in a particular element are in a compound?
The number of atoms of a particular element in a compound can vary depending on the chemical formula of the compound. You can determine the number of atoms by looking at the subscripts in the chemical formula. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
