Test Tube 1: 0.25 mol/L
Test Tube 2: 0.20 mol/L
Test Tube 3: 0.15 mol/L
Test Tube 4: 0.10 mol/L
Test Tube 5: 0.050 mol/L
Step-by-step explanation
The first test tube consists of only the 0.25 M CuSO4 solution and no distilled water so its concentration must be 0.25 M. The following test tubes are then diluted versions where CuSO4 makes up, respectively, 80%, 60%, 40%, and 20%, of the 10 mL solution. The concentrations of these solutions will then be, respectively, 80%, 60%, 40%, and 20% of the concentration of test tube 1.
