What is the difference between molecular weight in amu and molecular weight in grams?
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules.
The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.

Molecular weight of petrol?
The molecular weight of petrol can vary based on its composition, but it is typically around 114-120 grams per mole. This is a rough average as petrol is a mixture of hydrocarbons with different molecular weights.
A sample of sweet corn weighing 175 grams was freeze dried The recovered solid weighed 122 grams What was lost?
The difference between the original weight (175 g) and the recovered solid weight (122 g) is 53 grams. This 53 grams represents the loss in weight during the freeze-drying process.
What is KOH Molecular weight?
K - 39.10O - 16.00H - 1.01---- = 56.11 g/mol!Just add the three individual atomic masses together to get the molecular mass. Hope this helps.
What is the molecular weight of 7H2O?
Ah, the molecular weight of 7H2O, or water, is about 126.14 grams per mole. Isn't that just a lovely number? Remember, understanding the molecular weight helps us appreciate the beauty and harmony of chemistry.
How do you convert molecular weight from Dalton to grams?
To convert molecular weight from daltons to grams, you use the molar mass constant, which is 1 g/mol = 1 dalton. Therefore, the molecular weight in daltons is equivalent to the molar mass in grams per mole. Simply express the molecular weight in grams per mole.
What is the molecular weight chlorine?
The molecular weight of chlorine is 35.453 grams per mole.
What is the molecular weight of H2?
The molecular weight of H2, which is a diatomic molecule of hydrogen, is approximately 2.01588 grams per mole.
What is the difference between formula mass and the molecular mass of a compound?
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
What is the molecular weight of a compound in daltons converted to grams per mole (g/mol)?
To convert the molecular weight of a compound from daltons to grams per mole (g/mol), you need to divide the molecular weight in daltons by the Avogadro constant (6.022 x 1023). This will give you the molecular weight in grams per mole (g/mol).
What are mol?
the molecular weight of a substance expressed in grams
What is the molecular weight of carbon?
The molecular weight of carbon is 12.0107 g/mol, or grams per molecule. This is calculated by dividing the total weight of the atom by the weight of all the atomic mass units and multiplying by 100.
Is ammonia vapor heavier than nitrogen?
Yes, ammonia vapor is heavier than nitrogen. The molecular weight of ammonia (NH3) is 17 grams per mole, while nitrogen (N2) has a molecular weight of 28 grams per mole. This difference in molecular weight causes ammonia vapor to be denser and heavier than nitrogen gas.
