Astudent performs an experiment that produces solid sodium chloride. he uses four different catalysts and lets the reaction run for two minutes, and then removes the sodium chloride product. which is the best way for him to make a consistent measurement that would show the different amounts of sodium chloride produced? (2 points) measure the product separately on four different scales. measure all of the product together and divide by four. measure the four products separately, but using the same scale each time. measure the amount of sodium chloride in one sample every 10 seconds.

He should measure the products separately but on the same scale

Explanation:

different scales work a little bit differently so your data would not be super accurate

each sample could and should be of different masses because you used different catacysts so finding the average won't help you in any way

measuring every 20 seconds would change your data because it would be in a different state of reaction so the amount of sodium chloride would change drastically

thus, the only reasonable answer is to measure them separately (to get the individual mass and to help you see how each catcylst affects the amount of sodium chloride made) and to meaure them on the same scale(most accurate results)

He should measure the products separately but on the same scale
