An unknown food-dye is analyzed by the method used in this experiment. The absorbance of 5 standard solutions is plotted vs. their concentration (molarity) and a straight line is obtained with the formula: Abs = 3.350x +0.08 An unknown food-dye soluton is diluted and it's absorbance is found to be 0.50. What is the molarity of the diluted unknown, to two significant figures?
