## What is the difference between gram atomic mass and gram molecular mass?

The key difference between gram atomic mass and gram molecular mass is that the gram atomic mass gives the mass of an individual atom while the gram molecular mass gives the mass of a group of atoms. Atomic mass and molecular mass (or molar mass) are very important regarding atoms and molecules.

What is the difference between molecular mass and atomic mass?

The atomic mass corresponds to the mass of an element, while the molecular mass corresponds to the mass of a chemical compound.

What is the difference between gram atomic mass and gram molecular mass explain with the help of an example?

When atomic mass is defined in terms of gram it is known as gram atomic mass. When molecular mass is defined in terms of gram it is known as gram molecular mass. ExplanationAtomic weight if oxygen is 16amu. 1 mole of oxygen is 6.02×10^23 therefore 1 amu =1.661×10^-24gram.

### What is the molecular mass of a water molecule?

18.01528 g/molWater / Molar mass
The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

Which of the following has the same value of gram atomic mass and gram molecular mass?

Element whose gram atomic mass and gram molecular mass are the same is Argon.

What is the molecular mass of water?

Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen’s is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.

#### Is gram atomic mass and molar mass same?

Gram atomic mass is the periodic table element’s atomic weight in grams. The molar mass of an element is the mass of one mole in grams. The mass of one mole of an element is defined as its gram atomic mass. It is calculated by taking an element’s atomic weight from the periodic table and converting it to grams.

What is the difference between co2co2 and 2co22co2?

The substance with the chemical formula is called as carbon dioxide, whereas ( )is called as dicarbon dioxide. Carbon dioxide is composed of 1 atom of carbon and 1 atom of Oxygen, whereas dicarbon dioxide is composed of 2 carbon atoms and 2 oxygen atoms.

What is the difference between molecular weight and atomic weight?

Atomic mass gives the mass of atoms while molecular weight gives the mass of molecules. However, the key difference between atomic mass and molecular weight is that the atomic mass is the mass of a single atom whereas the molecular weight is the sum of the weights of the atoms in the molecule.

## What is the molecular mass of h2o?

18.01528 g/molWater / Molar mass

What is the difference between structural formula and molecular formula?

What is the difference between molecular formula and structural formula? The molecular formula is just the elements of the molecules with the number of elements. The structural formula is drawing the structure of the molecule.

What is the difference between Gram atomic mass and Gram molecular mass?

Therefore, the key difference between gram atomic mass and gram molecular mass is that the gram atomic mass gives the mass of an individual atom, while the gram molecular mass gives the mass of a group of atoms. 1. Helmenstine, Anne Marie. “Gram Molecular Mass Definition.”

### What is the difference between molar mass and atomic mass of water?

Difference Between Molar Mass and Atomic Mass. Water is also known as H2O. It is composed of two hydrogen atoms and one oxygen atom. An oxygen atom weighs 16 grams per mole. A hydrogen atom weighs 1 gram per mole. So multiplying 2 hydrogen atoms would yield 2 grams per mole of hydrogen plus 16 grams per mole of oxygen equals 18 grams per mole.

What is the mass of 1 mole of water in grams?

Molecular mass is the mass of 1 molecule and gram molecular mass is the mass of 1 mole molecules (just to keep the numeric value same). while mass of 1 mole of water is 18 g . So thus 18 g is also known as water’s gram molecular mass. You may note that the numeric value is same. Hope this helps !!!

What is the difference between molecular mass and molecular weight?

Molecular mass or molecular weight is the weight of molecule in atomic mass units . for example mass of H2SO4 molecule is 98 amu . gram molecular mass is the mass of 1 mole of that compound (1 mole is avogadro number of molecules or atoms which is 6.023 × 10^23 )
