A body has relative density 7.8. What will be its density in M.K.S units?
Step 1: Given data,The relative density of the body is = 7.8We know that the density of water at 4∘Cis = 1000kg/m3
Step 2: Finding the density of the body,relativedensity=densityofbodydensityofwaterat4∘ CSo,densityofbody=relativedensity×densityofwaterat4∘ C=7.8×1000kg/m3=7800kg/m3
Hence, the density of the body is 7800kg/m3.
The density of iron is 7.8 ×103 kg m−3. What is its relative density ?
The relative density of a metal alloy is 5.6. Its density in SI units will be
