Question

The density of a substance is 3.4 g cm-3. Its relative density relative to another substance is 2.0. what is the density of the second substance?​

Answer 1

Answer: The density of the second substance =
`1.7\text{ g cm}^(-3)`

Explanation:

`\text{Relative density }=\frac{\text{Density of substance}}{\text{Density of reference}}`

Given: Density of a substance is
`3.4 \text{ g cm}^(-3)` .

Its relative density relation to another substance = 2.0

Substitute all values in the formula , we get

`2=\frac{3.4}{\text{Density of reference}}\\\\\Rightarrow\ {\text{Density of reference}=(3.4)/(2)\\\\\Rightarrow\ {\text{Density of reference}=1.7 \text{ g cm}^(-3)`

Hence, the density of the second substance =
`1.7\text{ g cm}^(-3)`
