Water-soluble chitosan (WSC) is a derivative of chitosan.is the amount of a substance (in grams) that is numerically equal to its molecular weight. For example, one mole of carbon weighs 12.011 grams and one mole of monocalcium phosphate (Ca (H) weighs 234.05 grams. The number of molecules of a substance in one mole is 6.02 $\times$ 10, this number is known as. Sodium chloride (NaCl) has a …Physics questions and answers. 107 grams of liquid water are in a cylinder with a piston maintaining 1 atm (101325 Pa) of pressure. It is exactly at the boiling point of water, 373.15 K. We then add heat to boil the water, converting it all to vapor. The molecular weight of water is 18 g/mol and the latent heat of vaporization is 2260 J/g.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. The chemical formula for an ….

Convert grams KCl to moles. or.Molecular weight of petrol is so much higher than water, but when it comes to physical property, weight, one litre of water weighs more than one litre of petrol. ... Because the water molecule is shaped like a triangle, it is possible for the water molecules to "snuggle up" with each other, and pack themselves close together. Like this:Molecular weight. Molecular weight is the sum of the atomic weights of the atoms in a molecule . A molecule can be viewed as an entity of one or more different atoms bound together by some kinds of mutual interactions. As an example, the molecular weight of water , H2O, is calculated as (2 × 1.00797) + (1 × 15.9994) = 18.0153, where 1.00797 ......
