ability of a medium to attract water molecules is known as osmotic potential.
you may also label it as osmotic potential.
at a time a system has more water potential and low solute potential and vice versa.

If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
What factors affect water potential?
solute concentration and pressure
Could you calculate the molarity of a solution you need to know the moles of solute and the?
volume of the solution
How do you calculate the molecular weight and the uncertainty of the molecular weight of a unknown solute using propagated error?

How can methylene blue change the solute potential of the cell?
Methylene blue is a membrane-permeable dye that can enter the cell and bind to cellular components, such as proteins and nucleic acids. This binding can alter the osmotic properties of the cell and affect its solute potential. Methylene blue can also disrupt the electron transport chain in mitochondria, leading to changes in cellular metabolism and solute potential.
When does water potential decrease?
The water potential is really just the sum of the pressure potential and the solute potential. Obviously, then, lower pressure potential would lower the water potential, and so would lower solute potential. To lower the solute potential, the moles of the solute would actually have to increase. This probably seems backwards, but the equation for solute potential is -iCRT (where C is moles/liter, for some reason). Because there's a negative sign, the more moles you have, the less the solute potential is. Hopefully that helps.
How does the addition of solutes affect water potential?
adding the solute raises the boiling point of the water.
Is solute potential same as osmotic potential?
yep!
Which factors affect water potential in living cells?
Some factors which influence water potential include gravity, pressure, and solute concentration. Adding solute lowers the water potential. An increase of pressure will increase the water potential.
What is the osmosis definition?
"Osmosis is the diffusion of a solvent (frequently water) through a semi-permeable membrane, from a solution of low solute concentration (high water potential) to a solution with high solute concentration (low water potential), up a solute concentration gradient."
To calculate the molarity of a solution, you need to know the moles of solute and the?
You need to know the moles of solute and the VOLUME of SOLUTION.
Why is the water potential of distilled water higher than the water potential of the cytoplasm of the cell?
distilled contain no solute. so, its water potential is constantly 0. plant cell carry out photosynthesis continuously to produce sugar. thus, cytoplasm of plant cell always contain solute that lower the water potential of cytoplasm.
Why does the addition of a solute with polar molecules to one side of a membrane result in diffusion of water?
Addition of a polar solute lowers the water potential on that side of the membrane and so water will diffuse from the other side of the membrane from a relatively high water potential to the lower water potential, by osmosis.
If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
What factors affect water potential?
solute concentration and pressure
How do you calculate parts per million?
In chemistry, parts per million or ppm is defined as the number of part of a solute that is in one million parts of a solution. The formula to calculate ppm is to divide the mass of the solute in grams by the combined mass of the solvent and solute also in grams. This value is multiplied by 1,000,000 ppm.
What is the water potential of an open beaker full of pure water?
Pure Water has potential of 0.If more solute is added to it water potential falls-it becomes more negative
