A class has two yellow powders. They measured some properties of each of the powders. Students used the samples and recorded color, mass, density (a measure of mass per volume), and tested to see if the powders dissolved in water and if they burn in air. Their data are summarized in the table below. Properties of Powders
Color Mass (grams) Density
(grams per cubic centimeter) Dissolves in Water Burns in air
Powder 1 Yellow 12.6 1.56 Yes Yes
Powder 2 Yellow 18.2 1.89 Yes No
Which measurement cannot be used to determine whether the two powders are the same substance?

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
