i have researched the answer and it is
10.0266
Mass one molecule H2O = (Molecular weight H2O in grams)/(Avogadro's no.)
= (15.9994+1.00794*2)/(6.02214129×1023 mol−1)
= 2.9915(1)×10-23 grammes (exact)
A molecule of water has one oxygen atom and two hydrogen atoms. Their atomic masses are 16 and 1 respectively. Therefore the GMM of water is 16+2x1=18g.
This mass in grams is the ratio between 18 and 6,022 140 857.1023.
1 molecule of water = 3.10-23 g
The mass is approx 2.99*10^-23 grams.
18.01 g/mol
The formula for water molecule is H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
One single water molecule is....two hydrogen atoms bonded to one oxygen atom with molecular weight 18.016. You will never see one molecule of water as that is too small to view without special equipment.
Molecule
In a single molecule of water, there are three atoms. There are two hydrogen (H) atoms and one oxygen (O) atom.
The definition of a molecule is two or more atoms which have chemically combined to form a single species. Therefore when the two hydrogen atoms combine with the one oxygen atom, you get a single substance.
no
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
A tablespoon is not a molecule, but it can hold things that contain molecules. A tablespoon of water weighs about 15 grams. There are an enormous amount of molecules in water.
A single molecule. If you split that up, it will no longer be water.
The formula for water molecule is H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
That would depend on the element or molecule. Use the atomic weights of each of the atoms in the molecule in question and add them together this gives you the molecular weight. Such as H2O (water) = 1.01 +1.01 +16.00 = 18.02 the units for this is grams per mole. To convert grams to moles you take the number of grams you have and divide it by the molecular weight of the molecule. If you had 2440 grams of water, you take 2440 grams/18.02 grams per mole and you get 135.405 moles of water. If you had 2440 grams of oxygen (O2), you would take 2440 grams/32.00 grams per mole and you get 76.25 moles of oxygen.
One single water molecule is....two hydrogen atoms bonded to one oxygen atom with molecular weight 18.016. You will never see one molecule of water as that is too small to view without special equipment.
A normal water molecule weighs roughly 18 Amu's, so one mole of water weighs 18 grams. -KRogersaurus
No, Water is a molecule with hydrogen and oxygen
Molecule
The chemical bond in water is covalent.
Scientists estimate that it can take a single water molecule as long as 4000 years to complete one cycle.
