Troy measures the mass of two substances as shown in the picture. Which conclusion is best supported by Troy's measurement?

• Substance S and substance T are different kinds of matter.

• Substance S and substance T are made of different elements.

• The amount of matter in substance T is greater than the amount of matter in substance S.

• Substance T is a fine powder.

• Substance T mixed in water is conductive.

• Substance T is made of irregular crystals.
