Question

The relative density of oak wood is 0.6. What is the density in 1. SI unit and in cgs system

Answer 1

Explanation:

Density = relative density of oak wood x density of water

= 0.64 x 1 g / cm³ = 0. 64 g / cm³

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
