A student performs a spectrophotometric analysis using external calibration and ottains a linear relationship with a slope of 0.0475 a.u./M and a yintercept of 0.017 a.u. In order to analyze an unknown solution, the student dilutes 5.00mL of the uniknown solution to 100.00mL If the absorbance of the dilute unknown solution is measured as 0.350, then what is the concentration of the unknown solution?
