4. The test solution has an optical density of 0.90 when measured in a cuvette with a layer thickness of 5 cm. Calculate its concentration (µg/ml) if a standard solution containing 5 µg/ml of the same substance has an optical density of 0.6 when measured in a cuvette with a layer thickness of 3 cm.
