A scientific technique can be used to determine the presence and concentration of a chemical compound in a sample. A light source is directed at samples of known concentrations and the amount of light each absorbs is measured. Based on the graph, which statement best describes the relationship between concentration and light absorption? A. The light absorption of a sample is independent of the concentration of the chemical compound.
B. The concentration of the chemical compound in a sample remains steady as the light absorption increases.
C. An increase in the concentration of the chemical compound in a sample is accompanied by an increase in the light absorption.
D. A decrease in the light absorption of a sample is accompanied by an increase in theconcentration of the chemical compound.
