19. Suppose the students had mixed a 12.5 g sample of Margarine B and a 12,5 a samplerde Margarine C. Further suppose that they had tested this mixed sample following the procedure
from Experiment 1. Based on Table 1. predict the most likely mass, in grams, of water in the
mixed sample. Explain your answer using specific numbers from Tablel.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
