I finally figured out how to answer this question if you still need the help for it.
you use the osmotic pressure equation: TT = (M)(R)(T)
R= .08206 L*ATM/mol *k (this is your constant)
T= temperature in Kelvin 300K
TT=Pressure in ATM 8.95
Now you have to (M) Molarity. 8.95atm/.08206*300= .3635 mols/1L
now multiply that in a chain of conversions=
0.3635mols/L*342.12 g/mol(MM of sucrose)*472ml(grams of water since 1g is equal to 1ml)= 58698 and then divide by 1000 to cancel out L and ml= 58.69g
of sucrose
Now add this to your grams of water = 472+58.69=530.69g
( the question says you have so and so water in a solution so that's why you add the sucrose to get your amount of solution needed)
that mass 530.69 you convert to Liters= .53069L and then multiply that with your molarity at the top and you cancel out Liters and left with mols= .1929 mols.
then find the mass of sucrose needed by multiplying the .1929 mols* 342.12g and theres your answer.
The cell lose water in the hypertonic solution, which has higher osmotic pressure.
Its neutrality in not affecting the osmotic pressure of a cell.
They add more solute particles into the solution and have a greater effect on osmotic pressure.
Tonicity is measure of the effective of osmotic pressure. Osmosis is the minimum pressure which needs to be applied to a solution.
osmotic pressure=CRT x i 25 C to Kelvin = 298K 0.318atm= 0.010 M x 0.08206 x 298 K answer= 1.30
osmorality
This a saline solution with the concentration of 0,9 g NaCl/100 mL distilled water. This is a isotonic solution; the meaning is that the osmotic pressure of the this solution is equal to the osmotic pressure of the blood serum.
This is a solution having an osmotic pressure identical with the pressure inside the cells of the human body.
a solution that has a higher osmotic pressure than another solution to which it is compared
When a plant cell is placed in a hypotonic solution, the osmotic pressure tends to increase as the water in the cells moves to a place elevated in solute concentration. The osmotic pressure is the chief cause of support in numerous plants.

The cell lose water in the hypertonic solution, which has higher osmotic pressure.
The osmotic pressure. This is the pressure which would have to be applied to a solution to stop water entering if it was separated from pure water by a semipermeable membrane.
applying a pressure equal to the osmotic pressure on the more concentrated solution side.
Isotonic solution.
A hypertonic solution does shrink. It is when the osmotic pressure is greater than the solution that is within it.
