Question

Density of aluminium is 2700 kg m-3. What is its relative density ? Density of water is
1000 kg m-3. Define relative density. plls solve​

Answer 1

Answer:

relative density of aluminium =2700/1000=2.7

Answer 2

Explanation:

Given:

• Density of aluminium,

$\rho=2700\ kg.m^{-3}$

• Density of water, $\rho_w=1000\ kg.m^{-3}$

As we know that relative density is the ratio of the density of the given substance to the density of water.

So,

$S= \frac{\rho}{\rho_w}$

$S= \frac{2700}{1000}$

$S=2.7$
