HOW TO DETERMINE THE DENSITY OF A KEROSENE

density is mass/volume

THROUGH PRACTICALISATION

To determine the density of kerosene, you can follow these steps:

1. Obtain a sample of kerosene: Ensure that you have a sufficient amount of kerosene to conduct the measurement accurately. The sample should be clean and free from any impurities that could affect the density measurement.

2. Prepare a clean and dry container: Use a glass or plastic container that is clean, dry, and free from any contaminants. Make sure the container is large enough to hold the kerosene sample and has a known volume. The container should have a narrow opening to prevent any spills or evaporation.

3. Weigh the empty container: Before adding the kerosene, weigh the empty container using an analytical balance or a scale with high precision. Note down the mass of the container.

4. Add the kerosene to the container: Carefully pour the kerosene into the container until it reaches a desired level. Avoid introducing air bubbles into the liquid.

5. Weigh the container with the kerosene: Once the kerosene is added, weigh the container again with the kerosene inside using the same balance or scale. Record the mass of the container with the kerosene.

6. Calculate the density: To determine the density of the kerosene, use the formula: Density = Mass of kerosene / Volume of kerosene. The mass of the kerosene is the difference between the mass of the container with the kerosene and the mass of the empty container, while the volume of kerosene can be calculated using the known volume of the container.

For example, if the mass of the empty container is 100 grams and the mass of the container with the kerosene is 150 grams, and the container has a volume of 200 milliliters, then the mass of the kerosene is 150 grams - 100 grams = 50 grams, and the volume of the kerosene is 200 milliliters. Therefore, the density of the kerosene would be 50 grams / 200 milliliters = 0.25 grams/mL.

Remember to use consistent units throughout the calculation, either metric (grams and milliliters) or imperial (ounces and fluid ounces).

By following these steps and performing the necessary calculations, you will be able to determine the density of kerosene.
