A scientist is doing an experiment to see how oxidation affects the mass of iron-based metals Which of the following instruments would best help the scientist determine the results of his study?

Answer 1

a balance.

Answer 2

A balance scale would be the best instrument for the scientist to use in order to measure the mass of the iron-based metals before and after exposure to oxidation. This would allow the scientist to determine any changes in mass due to the oxidation process.
