Water potential practice

The value for  $$\Psi$$  in root tissue was found to be -3.3 bars.  If you take th root tissue and place it in a 0.1 M solutin of sucrose at 20 $$\degree$$ C in an open beaker, what is the  $$\Psi$$  of the solution, and in which direction would the net flow of water be?

The original cell from question 1 is pllaced in a beaker of sugar water with  $$\Psi s$$  = -0.15 MPa (megapascals).  We know that 1 MPa = 10 bars.  In which direction will the net flow of water be?

If a cells $$\Psi p$$ = 3 bars and its  $$\Psi s$$ = -4.5 bars, what is the resulting  $$\Psi$$  ?

At 20 $$\degree$$ C, a cell with  $$\Psi p$$  of 3 bars is in equilibrium with the surrounding 0.4M solution of sucrose in an open beaker.  What is the molar concentration of sucrose in the cell?

What is the $$\Psi s$$   of a 1.0M sugar solution at 22 $$\degree$$ C under standard atmospheric conditions?

At 22 $$\degree$$ C, zucchini cores are measured and determined to have a sucrose concentration of 0.36M. What is the $$\Psi s$$   of these cells and in which direction will the net flow of water be?

A plant cell with a $$\Psi s$$  of -7.5 bars keeps a constant volume when immersed in an open-beaker solution that has a  $$\Psi s$$  of -4 bars.  What is the cells  $$\Psi p$$  ?

At 20 $$\degree$$ C, a cell with  $$\Psi p$$  of 3 bars is in equilibrium with the surrounding 0.4M solution of sucrose in an open beaker.  What is the molar concentration of sucrose in the cell?

What is the pressure potential for pure water in an open container?
