6.022 * 10^23 = 1 mole
3.011 * 10^23 = 1/2 a mole
Magnesium sulfite has 6 water molecules.
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
An octahydrate contains 8 water molecules per formula unit.
2.60x10^23 water molecules contain 2.60x10^23 molecules of water.
Since a mole is approximately 6.02 x 1023 molecules, half a mole would be about 3.01 x 1023 molecules.
Your question is irrelevant. I think that you were trying to find the number of molecules present in half a mole of water. 1 mole of water contains 6.023 * 1023 number of molecules. Hence half mole contains half of that number of molecules which is 3.0115*1023.
The answer is 0,166.10e23 molecules.
there are 2 atoms of hydrogen in water

it would be 2 L not 2 Kg
In pure water, there are no calcium ions.
Water molecules are H2O so there are 2 Hydrogens bonded to 1 oxygen.
An octahydrate contains 8 water molecules per formula unit.
H2O consists of two Hydrogen and one Oxygen. Three sets of these would mean 9 atoms in your three molecules of water.
depends on what salt it is and the purity of the water. if the water is 100% pure , then it contains only hydrogen and oxygen as molecules and if it is common salt then it contains sodium and chlorine as molecules
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
