How can we determine the R.D of solid lighter than water. (Formula).
Answers
Answer:
Explanation:
You can easily find R.D of any solid (regular) if you know its dimensions
no matter what mass it has .
Relative Density = Density of solid / Density of Water
Density of water is 1000 kg/m^3 or 1 gm/cm^3
Density of any solid = Mass/Volume
If you the know dimensions ( length , breadth , height or radius etc)
you can easily calculate volume and weigh it on a spring balance to get its mass.
Then use the formula to get the Density of the solid
To get RD divide the resulting density of the solid with the density of water with the value suiting your units i.e 10000 for SI system or 1 for cgs
Note : Your units for the density of the solid MUST be the same
For example if the density of the solid I have is 9000 kg/m^3 then I will use 1000 to get the RD
Extra : Relative density has no units.
