specific gravity formula

To calculate the specific gravity, you can use the following formula:

Specific Gravity = Density of the substance / Density of water

Here are the steps to calculate the specific gravity:

1. Determine the density of the substance: The density of a substance is its mass per unit volume. You can find the density of the substance by dividing its mass by its volume. The units of density are typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

2. Determine the density of water: The density of water is approximately 1 gram per cubic centimeter (g/cm³) or 1000 kilograms per cubic meter (kg/m³).

3. Divide the density of the substance by the density of water: Divide the density of the substance by the density of water using the formula mentioned above. This will give you the specific gravity of the substance.

For example, let's say you have a substance with a density of 2.5 g/cm³. To calculate its specific gravity, you would divide 2.5 g/cm³ by 1 g/cm³ (density of water). The specific gravity would be 2.5.

Remember, specific gravity is a dimensionless quantity and does not have any units. It is a ratio of the density of the substance to the density of water.
