Question

relative density of any substance is 0.64 find its density in SI system ​

Answer 1

Answer:

Relative density is defined as: dr = ds / dw where: dr: relative density ds: density of the substance. dw: density of water. In this case we have the relative density of oak wood: dr = 0.64. We want to find the density of the substance: ds Therefore we need to know the density of water in the cgs unit system: dw = 1g / c ^ 3 Finally: ds = dr * dw ds = 0.64 * 1 g / cm ^ 3 ds = 0.64 g / c ^ 3 The density of the oak wood in cgs is 0.64 g / cm ^ 3.

Answer 2

The relative density of substances is 0.64 .. it means the density of the body is 640kg/m^3 .....

As you know RD= density of substances / density of water at 4°C .....
