Why would crystals diffuse faster in hot water than in cold water?
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.
Is a 2 percent salt solution hypertonic or hypotonic to a 4 percent salt solution?
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.
Would sugar's starch or salt diffuse faster in a dialysis bag?
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.
What is the percentage by mass of salt solution prepared by dissolving 11 grams of salt in 80 grams of solution with solution?
The percent concentration is 13,75 %.
In a salt solution that is 15 percent salt what percent is water?
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%.
How much salt must be added to 60kg of a 20 percent solution of salt to increase it to 40 percent solution of salt?
20%
How many gallons of 3 percent salt solution must be mixed with 50 gallons of 7 percent salt solution to obtain a 5 percent salt solution?
50 gallons @ 3% must be added.
What is 2 percent salt solution to a 4 percent salt solution?
Twice Half as strong. Really? What the heck kind of question is this?

A 280 mL solution is 20 percent salt How much water should be added to make the solution 14 percent salt?
98 mL
How many liters of 9 percent salt solution and 18 percent salt solution are needed to make 18 liters of 10 percent salt solution?
A. 16 of 18 percent and 2 of 9 percent b. 14 of 18 percent and 4 of 9 percent c. 16 of 9 percent and 2 of 18 percent d. 14 of 9 percent and 4 of 18 percent

How many gallons of a 9 percent salt solution must be mixed with 25 gallons of a 31 percent solution to obtain a 20 percent solution?
25 gallons
How would you make 22.3 percent salt solution?
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.
A chemist has m gm of salt water that is m percent salty so how many gram of salt must be added to make a solution that is 2m percent salty?
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.
