Crystals diffuse faster in hot water because the heat increases the kinetic energy of water molecules, making them move more rapidly and allowing for quicker diffusion of the dissolved particles from the crystal. The increased temperature also decreases the viscosity of the water, which reduces resistance to the diffusion process.
A 2% salt solution is hypotonic compared to a 4% salt solution because it has a lower concentration of salt. In osmosis, water flows from hypotonic to hypertonic solutions, so in this case, water would flow from the 2% solution to the 4% solution to try to equalize the concentrations.
When considering a dialysis bag, size will determine whether the molecules will permeate the bag. The smaller the molecules, the easier they well be able to pass through, and the faster diffusion will take place. Starch is a carbohydrate - a macromolecule formed from repeating bonded units of glucose monomers. Salt, in comparison, is simply Na+ and Cl- ions (in the aqueous solution). Starch will have a much tougher time getting through the artificial membrane, so it is a safe bet that salt will diffuse faster.
The percent concentration is 13,75 %.
It depends, is the solution 15% salt or 15% saturatedwith salt? If it is 15% salt, is is 85% water. If it is 15% saturated, it is 5.385%.

Twice Half as strong. Really? What the heck kind of question is this?

To make a 22.3% salt solution, you would dissolve 22.3 grams of salt in 100 grams of solution (salt + water). This would result in a solution where 22.3% of the total weight is salt.
To convert the solution from m percent salty to 2m percent salty, you need to add m/2 grams of salt. This will ensure that the ratio of salt to water in the solution is doubled, resulting in a 2m percent salty solution.
