The denser a substance, the more tightly packed it is. The table below shows the volume and mass of two different substances. Co

trasher [3.6K]

Answer:

Both objects are packed equally tightly.

Explanation:

For Substance R we have

mass = 10 g

Volume = 22 cubic cm

So we know that density is defined as

$\rho = \frac{m}{V}$

here we have

$\rho = \frac{10 g}{22 cm^3}$

$\rho = 0.454 g/cm^3$

For substance S we have

mass = 25 g

Volume = 55 cubic cm

So we know that density is defined as

$\rho = \frac{m}{V}$

here we have

$\rho = \frac{25 g}{55 cm^3}$

$\rho = 0.454 g/cm^3$

So here both have same density

so correct answer would be

Both objects are packed equally tightly.
