Situation: A 25 gram sample of a substance that's
used for drug research has a k-value of
0.1229.
N = Noe -kt
No = initial mass (at time t = 0)
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

sorry

Step-by-step explanation:

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
