1.) a student wants to determine the effect of salt concentration on light transmittance. based on this table, what is the independent variable? a.) number of trials b.) salt concentration c.) light transmission d.) location of each trial

A because number of trials is independent mark me brainliest

Salt concentration

Explanation:

The independent variable can be defined as the factor which can be controlled in the experiment. The experimenter can control the amount of salt concentration in the experiment.

The dependent variable is the transmittance which is affected by the salt concentration. This factor is not under the control of the experimenter.

Hence, the correct answer is salt concentration.
