3. (5 Points) How many grams of NaNO, are required to saturate 100 grams of
water at 80°C?
4. (5 Points) At what temperature would 25g of potassium chlorate (KCIO)
dissolve?
5. (5 Points) A saturated solution of KCIO, was made with 300g of water at 40
degrees celsius. How much KCIO, was dissolved?
6. (5 Points) A saturated solution of KNO, was made with 200g of water at 50
degrees celsius. The solution was cooled to 20 degrees celsius. How much
KNO, precipitated out?

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.
