Calibration curve


The known solutions were placed in cuvettes for the colorimeter. One cuvette had only water as a blank. The colorimeter was set to zero for the cuvette with zero dye. The scale readings for the others were:
 
 
Concentration in cuvette    Scale reading (arbitrary numbers, depends on the colorimeter)

   1.83 g/L                          22.1
   0.0915                             3.8
   0.0183                             2.0
   0.00915                            1.9
   0                                   0
Here is the graph:

Is this an acceptable calibration curve ?
