The original solution was diluted by a factor of three, and then the absorbance of the diluted cereal sample solution was measured and recorded as (2.0x10^-1). Use the following trendline and dilution factor to determine the concentration of iron, in unit of M, in the original cereal sample solution. The trendline (linear regression) as displayed on the plot is y = 11898x - 0.0112.
