Determining the concentration of unknown solution using uv-vis spectroscopy. The absorbance vs concentration has an equation of straight line of y=8.4052x+0.0002 with r2=1. The unknown solution's absorbance is 0.150. From 75 mL sample, A 15 mL aliquot was examined. The 15 mL aliquot was mixed with 15 mL 1% percent by mass over volume HCl and was diluted to 40 mL with water. What is the concentration of the solution in the 75 mL sample?
