When finding density, make sure to measure the volume accurately using a graduated cylinder or displacement method. Use a balance to measure mass carefully. Avoid air bubbles when measuring volume, and ensure the substance is homogeneous. Triple-check your calculations to ensure accuracy.
1. ensure that when all readings are taken , your eye is perpendicular to the lower meniscus of the substance you are measuring
2. when lowering the object into container with water in it, do so carefully to avoid splashing. preferably with a string attached
Drop the solid gently in the liquid
Let your eyes be place on the graduated cylinder to avoid error due to parralex
ensure to wash and dry solid to remove loose pieces before placing it in water.

The density of water is often used as a reference point for measuring the density of other substances. Since water has a density of 1 g/cm^3 at 4 degrees Celsius, it serves as a benchmark when comparing the density of different materials. By knowing the density of water, scientists can easily determine the density of other substances by comparing their density to that of water.
None. Disaster management is a good thing that should be encouraged, not prevented.
The region of zero electron density is called a "node."
