how will you find relative density of coconut oil with the help of density bottle

To find the relative density of coconut oil using a density bottle, you will need to follow these steps:

1. Clean the density bottle thoroughly using distilled water and dry it completely to ensure there are no remnants of liquids or impurities from previous uses.

2. Weigh the empty and dry density bottle using an electronic balance, and record this value. Let's call it the "initial mass" (IM).

3. Fill the density bottle with distilled water until it overflows slightly. Wipe off any excess water from the outside of the bottle.

4. Weigh the density bottle filled with water, again using the electronic balance, and record this value. Let's call it the "mass of density bottle + water" (MDW).

5. Empty the density bottle and dry it completely before proceeding to the next step.

6. Now, add a sufficient amount of coconut oil to the dry density bottle. Make sure to fill it completely but without overflowing, ensuring no air bubbles are trapped.

7. Weigh the density bottle filled with coconut oil using the electronic balance and record this value. Let's call it the "mass of density bottle + coconut oil" (MDO).

To calculate the relative density (RD) of the coconut oil, you can use the formula:

RD = (MDO - MDW) / (MDW - IM)

Where:
- "MDO" is the mass of the density bottle with coconut oil,
- "MDW" is the mass of the density bottle with water, and
- "IM" is the initial mass of the dry density bottle.

By subtracting the mass of the density bottle with water from the mass of the density bottle with coconut oil and dividing it by the difference between the mass of the density bottle with water and the initial mass, you can find the relative density of the coconut oil. The relative density is a dimensionless quantity, so it is often expressed as a decimal number.
