A41.1 g sample of solid co2 (dry ice) is added to a container at a temperature of 100 k with a volume of 3.4 l. a. if the container is evacuated (all of the gas removed), sealed, and then allowed to warm to room temperature t = 298 k so that all of the solid co2 is converted to a gas, what is the pressure inside the container?

Approximately 6.81 × 10⁵ Pa.

Assumption: carbon dioxide behaves like an ideal gas.

Explanation:

Look up the relative atomic mass of carbon and oxygen on a modern periodic table:

Calculate the molar mass of carbon dioxide :

.

Find the number of moles of molecules in that sample of :

.

If carbon dioxide behaves like an ideal gas, it should satisfy the ideal gas equation when it is inside a container:

,

where

Rearrange the equation to find an expression for , the pressure inside the container.

.

Look up the ideal gas constant in the appropriate units.

.

Evaluate the expression for :

.

Apply dimensional analysis to verify the unit of pressure.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
