1. explain how to change a dilute solution to a concentrated solution 2. what is the concentration of a solution expressed in g/100 ml, of 25 g of solute is dissolved in 40 ml of water 3. why is water referred to as the universal solvent? is this description of water accurate (THIS IS SCIENCE)

1)By adding solute to the solution

2)25g/40ml =5g/8ml

3)Because all soluble solutes dissolve in water

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
