Do potato cubes gain or lose mass in salt water solutions?
depends on the salt content of the potato and how concentrated the salt is. the more salt there is in the water than the potato- the more water will exit the potato which then loses mass.
In which direction would osmosis occur if 15 percent sugar solution is separated from a 25 percent sugar solution?
It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.
Will changing sucrose concentrations change the mass of the potato?
Yes, through a process called osmosis. Osmosis is the diffusion of water across a cellular membrane. Water flows from high concentrations to low concentrations. The mass of the potato will change based on the molarity of the solution it is placed in. CHEMISTRY REFRESHER: molarity is the amount of moles of a substance per liter(of water). If the potato is placed in a solution with a lesser molarity than itself(the solution has less glucose than the potato) then we would expect for the potato to gain water. This is because there is a greater concentration of water outside of the cell wall, so water enters the cell in order to obtain equilibrium. Using the same reasoning we would expect for the potato to lose water if it is placed in a solution of higher molarity
Test tube contains red blood cells and a salt solution When the tube is held up to a page you cannot see the print with reference to a concentrationof 0.9 percent how concentrated is the?
0.9% NaCl = 9gm per litre which is isotonic with the red blood cells and as aresult the cells do not gain or lose water by osmosis and so remain in suspesion.
What will happen when rbc kept in 10 percent glucose solution?
As he concentration of sugar is higher at the outer atmosphere of rbc it will gain sugar inside and loss water
What percent gain is 88 to 102?
15.9% gain.
What is percent recovery in protein purification?
When you use methods such as Solvent precipitation, you precipitate a protein molecule but this protein molecule normally does not have the same structure as that of protein in a solution (for example disulfide bonds do not connect the same amino acids) and it is not easy to change this to that of original structure even when the same solution is present. The percent of recovery means the percent that these denatured protein molecules can gain the same structure that they have in the solution before precipitation.

Cost price of 10 mango is Rs18 and selling price is Rs21what is the gain in percent?
If ten mangoes cost Rs 18 and selling them costs Rs 21, then there is a gain of Rs 3. This is a 16.7 percent gain.
