Osmium has a density of 22.6 g/cm^3. What volume (in cm^3) would be occupied by a 21.8 g sample of osmium?
Snowcat [4.5K]

0.9645 cm³ is the occupied volume by a 21.8 g sample of osmium of density of 22.6 g/cm^3.

Given values are:

  • Mass, m = 21.8 g
  • Density, d = 22.6 g

Density is given by,

  density = \frac{mass}{volume}

⇒volume = \frac{mass}{volume}

⇒volume = \frac{21.8}{22.6}

⇒volume = 0.9645 cm^3

∴The volume is 0.9645cm^3

3. give reasons
soldi70 [24.7K]

Answer:

A.A gas exerts pressure on the walls of the container. Reason: They have high kinetic energy and negligible force of attraction to move constantly moving with high speed in all directions. ... These collisions of the gas particles with the container walls exert pressure on the walls of the container.

B A gas exerts pressure on the walls of the container due to imapact of its gas molecules with hight velocity .

C.A wooden table should be called a solid. Reason: It has a definite shape and volume. It is very rigid and cannot be compressed, i.e., it has a solid characteristic.

D.We can easily move our hand in air but to do the same through a solid block of wood we need a karate expert. It is because the molecules of air has less force of attraction between them and a very small external force can separate them and pass through it.
