An unknown food-dye is analyzed by the method used in this experiment. Theabsorbance of 5 standard solutions is plotted vs. their concentration (molarity) and astraight line is obtained with the formula:Abs = 4.150x +0.08An unknown food-dye soluton is diluted and it's absorbance is found to be 0.65.What is the molarity of the diluted unknown, to two significant figures?Do not type units with your answer.Your Answer:

Given : Abs = 4.150x + 0.08Calculations: We know that , for straight line curve : y = mx + b where m = slope and x = concentration , b = intercept , y = absorbance Therefore, Abs = 4.150x + 0.08For concentration calculations:C = A-bslope=0.65-0.084.150=0.14
