Ethyl alcohol, commonly referred to as ethanol, is a widely used substance in various industries, including pharmaceuticals, food and beverages, and fuel production. Understanding its physical properties, such as density, is crucial for accurate measurements and applications. In this article, we will provide an in-depth look at the density of ethyl alcohol in g/ml, along with accurate values and a comprehensive guide.
What is Ethyl Alcohol Density?
Ethyl alcohol density, also known as ethanol density, is the mass per unit volume of ethyl alcohol. It is typically expressed in units of grams per milliliter (g/ml) or grams per cubic centimeter (g/cm³). The density of ethyl alcohol varies depending on its concentration, temperature, and pressure.
Factors Affecting Ethyl Alcohol Density
Several factors influence the density of ethyl alcohol, including:
- Concentration: The density of ethyl alcohol changes with its concentration in a solution. As the concentration of ethanol increases, its density decreases.
- Temperature: Temperature affects the density of ethyl alcohol. As temperature increases, the density of ethanol decreases.
- Pressure: Pressure has a minimal effect on the density of ethyl alcohol, but it can be significant at high pressures.
Accurate Values of Ethyl Alcohol Density in G/ml
The following table provides accurate values of ethyl alcohol density in g/ml at different concentrations and temperatures:
| Concentration (% v/v) | Density at 20°C (g/ml) | Density at 25°C (g/ml) |
|---|---|---|
| 10 | 0.9819 | 0.9803 |
| 20 | 0.9685 | 0.9669 |
| 30 | 0.9551 | 0.9535 |
