Given absorbance of unknown diluted solution is 0.65

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 = 2.250x An unknown food-dye solution is diluted and it's absorbance is found to be 0.65. What is the molarity of the diluted unknown, to two significant figures?
