I am given a test tube #1 with volume of 4Ml 0.390 M NiCl2 soultion , my absorbance is .0858, volume of H2o is 0 what is the concentration of NiCl2?

A student measured the absorbance of 4 different working standard solutions, and then constructed a calibration curve by graphing the concentration of each solution on the x-axis and absorbance for each solution on the y-axis. The resulting graph was a straight line (because there is a direct and linear relationship between concentration and absorbance). The equation for this straight line was found to be y = 1.438 x + 0.018 If the absorbance of an unknown solution is 0.252, what is the concentration of the unknown solution?
