122. When interferometrically determining the concentration of hydrochloric acid solutions, the following data were obtained:
Acid concentration, mol/dm3 0.205 0.400 0.605 0.805 1.05
Compensator readings 1.54 3.01 4.54 6.10 7.62

Construct a calibration graph and derive an equation for the dependence of the concentration of hydrochloric acid on the readings of the compensator scale. Determine the titer of a hydrochloric acid solution with respect to NaOH, if for this solution the scale reading is equal to:
Problem No. 122
Scale reading 2.75
