Here are the essential concepts you must grasp in order to answer the question correctly.
Density
Density is defined as the mass of a substance per unit volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³). It is a fundamental property that helps in identifying substances and understanding their behavior in different environments. In this context, the density of the urine sample is given as 1.030 g/mL, which is crucial for calculating its specific gravity.

Specific Gravity
Specific gravity is a dimensionless quantity that compares the density of a substance to the density of a reference substance, usually water at 4°C, which has a density of 1 g/mL. It is calculated by dividing the density of the substance by the density of water. Specific gravity provides insight into the concentration of solutes in a solution, making it particularly useful in medical diagnostics, such as evaluating urine samples.

Calculation of Specific Gravity
To calculate specific gravity, the formula used is: Specific Gravity = Density of the substance / Density of water. For the urine sample with a density of 1.030 g/mL, the specific gravity can be determined by dividing this value by 1 g/mL (the density of water). This calculation is straightforward and essential for interpreting the results in a clinical context.
