In water (H₂O), each hydrogen atom contributes one sigma electron, and the oxygen atom contributes two sigma electrons, resulting in a total of four sigma electrons per water molecule. The molar mass of water is approximately 18 grams per mole, so 9 grams of water corresponds to 0.5 moles. Therefore, the total number of sigma electrons in 9 grams of water is 0.5 moles × 4 sigma electrons/molecule × Avogadro's number (approximately (6.022 \times 10^{23}) molecules/mole), resulting in about (1.21 \times 10^{24}) sigma electrons.

What type of hybridization is present in water?
Water has sp3 hybridization around the oxygen atom, with two of the hybridized orbitals involved in forming sigma bonds with the hydrogen atoms and two lone pairs of electrons occupying the remaining two hybridized orbitals.
How many hydrogen atoms are present in 3.65 grams of water?
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.

What is sigma donar ligand?
A sigma donor ligand is a type of ligand that donates a pair of electrons to a metal center through a sigma bond. These ligands typically have lone pairs of electrons that can be shared with the metal, forming a coordinate covalent bond. Common examples include amines, phosphines, and water. Sigma donor ligands are essential in coordination chemistry and play a crucial role in the stability and reactivity of metal complexes.

How could you predict the presence of a sigma or pi bond in a molecule?
The presence of a sigma will be centered ( with the shared electrons) between the two atoms, such as in water H2O, the sigma will remain between the water and the hydrogen. It will remain in a bonding orbital between the two, the bonding orbital is the region where bonding electrons are likely to be found. As far a pi bond, you know already that there needs to be sigma in order to have a pi, if you have a double bond you can assume that there is one sigma and one pi, if there is a triple bond, you can assume that there will be one sigma and two pi. That's the best way I can explain it, .

How is cobalt chloride used to find out if water is present?
The cobalt chloride changes colour in the presence of water because of the different amount of protons and electrons that are present.
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
