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?
