The densities of crystalline co2 and nh3 at 160 k are 1.56 and 0.84 g/cm3, respectively. calculate their molar volumes.

The molar volume of carbon dioxide is and that of ammonia is

Explanation:

To calculate the molar volume for the given densities, we use the mass to be molar mass.

To calculate volume of a substance, we use the equation:

     ......(1)

Density of carbon dioxide =

Molar mass of carbon dioxide = 44.01 g

Putting values in equation 1, we get:

Hence, the molar volume of carbon dioxide is

Density of ammonia =

Molar mass of ammonia = 17.031 g

Putting values in equation 1, we get:

Hence, the molar volume of ammonia is

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
