# Solve Specific Gravity Problem: Cork Density 0.25 g/cc

• Ashford
In summary, specific gravity is the ratio of a substance's density to that of a reference substance. It is calculated by dividing the density of the substance by that of the reference substance. Specific gravity is important for determining purity, identifying substances, and in industrial processes. It can be measured using a hydrometer. The specific gravity of cork being 0.25 g/cc makes it less dense than water and suitable for various applications.

## Homework Statement

A piece of cork has a denisty of 0.25 g/cc. What is its specific gravity?

## Homework Equations

SG = Psubstance / PH20

## The Attempt at a Solution

I have no idea. was sick from class day of lesson.

Density of substance = $0.25 gcm^{-3}[/tex] Density of Water =[itex]1000kgm^{-3}$

convert one's units to the other and substitute.

I would first like to clarify that specific gravity is a measure of the density of a substance compared to the density of water. It is calculated by dividing the density of the substance by the density of water. In this case, the specific gravity of cork can be calculated by dividing its density of 0.25 g/cc by the density of water, which is 1 g/cc. This gives a specific gravity of 0.25 g/cc divided by 1 g/cc, which equals 0.25. Therefore, the specific gravity of cork is 0.25. I hope this helps and if you have any further questions, please feel free to ask.

## What is specific gravity?

Specific gravity is the ratio of the density of a substance to the density of a reference substance. It is also known as relative density.

## How do you calculate specific gravity?

To calculate specific gravity, divide the density of the substance by the density of the reference substance. In this case, the specific gravity of cork can be calculated by dividing its density of 0.25 g/cc by the density of the reference substance (usually water) which is 1 g/cc. This gives us a specific gravity of 0.25.

## Why is specific gravity important?

Specific gravity is important in many applications, such as determining the purity of a substance, identifying unknown substances, and in industrial processes. It can also provide valuable information about the physical properties of a substance.

## How do you measure specific gravity?

Specific gravity can be measured using a hydrometer, which is a device that measures the density of a liquid. The hydrometer is floated in the liquid and the specific gravity is read from a scale on the device.

## What is the significance of cork having a specific gravity of 0.25 g/cc?

The specific gravity of cork being 0.25 g/cc means that it is less dense than water (1 g/cc). This is why cork floats on water. It also means that cork is a lightweight material, making it suitable for various applications such as insulation, flooring, and wine bottle stoppers.
