Answer:
The water potential of a solution of 0.15 M sucrose solution is -3.406 bar.
Explanation:
Water potential = Pressure potential + solute potential
We have :
C = 0.15 M, T = 273.15 K
i = 1
The water potential of a solution of 0.15 m sucrose=
(At standard temperature)
The water potential of a solution of 0.15 M sucrose solution is -3.406 bar.
Answer:
35
Explanation:
An atom is neutral, meaning that the number of protons is equal to the number of electrons.
