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 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.
Dose water contain half as many hydrogen atoms as oxygen atoms?
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.
How many oxygen atoms are there in 3.45 grams of H2O?
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
How many atoms are in 2.25 mol of water?
The number of molecules is 15,055 352 142 5.10e23.
How many atoms are there in H2O?
Water contain thee atoms in the molecule.
What is the total number of oxygen atoms in the formula mgso47 h2o?
11
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.
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 times larger is the number of hydrogen atoms than oxygen atoms in a polysaccharide?
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
Dose water contain half as many hydrogen atoms as oxygen atoms?
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.
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 oxygen atoms are there in 3.45 grams of H2O?
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
How can the number of atoms of an individual element be determined by using a chemical formula?
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
How many time larger is the number of hydrogen atoms than oxygen atoms in a polysaccharide molecule?
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
How many oxygen atoms are in 12 h2o?
There is 1 O atom in 1 H2O molecule thus there are 12 O atoms in 12 H2O molecules.
How many atoms of oxygen are in one molecule of water (H2O)?
Just one. The formula of water is H2O. If there is no number after an element's symbol, then it is understood that there is one of that atom in the compound.
