Question

The denser a substance, the more tightly packed it is. The table below shows the volume and mass of two different substances. Comparison of Substances Substance Volume (cm3) Mass (g) R 22 10 S 55 25 Which of the two substances is more tightly packed? Object R is more tightly packed. Object S is more tightly packed. Both objects are packed equally tightly. This cannot be determined.

Answer 1

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.
