Question

Two chemists measure the densities of an unknown metal sample. They both find that the sample has a density of 8.94 g/mL. Chemist A uses a chart and says that the metal must be copper since the density of copper is exactly 8.94 g/mL. Chemist B says that the metal could be a mixture of two or three different kinds of metals with an average density of 8.94 g/mL.

Which of the scientists' conclusions could be valid?

a. Chemist A's conclusion is valid because it is supported by evidence.

b. Both scientists' conclusions could be valid.

c. Neither scientist's conclusion is valid because it is impossible to identify unknown substances.

d. Scientist B's conclusion is valid because most metals are alloys.

I think it's a

Answer 1

I guess it is kinda like chemistry lol. Can you help?? :)

Answer 2

Scientist B has it on the money.

Answer 3

the answer is c because they don't give you all the supporting details
