Answer: The density of the second substance = [tex]1.7\text{ g cm}^{-3}[/tex]
Step-by-step explanation:
[tex]\text{Relative density }=\dfrac{\text{Density of substance}}{\text{Density of reference}}[/tex]
Given: Density of a substance is [tex]3.4 \text{ g cm}^{-3}[/tex] .
Its relative density relation to another substance = 2.0
Substitute all values in the formula , we get
[tex]2=\dfrac{3.4}{\text{Density of reference}}\\\\\Rightarrow\ {\text{Density of reference}=\dfrac{3.4}{2}\\\\\Rightarrow\ {\text{Density of reference}=1.7 \text{ g cm}^{-3}[/tex]
Hence, the density of the second substance = [tex]1.7\text{ g cm}^{-3}[/tex]
