Problem: A piece of solid carbon dioxide with a mass of 5.60 g is placed in a 10.0-L vessel that already contains air at 710 torr and 24 °C.After the carbon dioxide has totally vaporized, what is the total pressure in the container at 24 oC?

FREE Expert Solution

We have to calculate the total pressure in the container when 5.60 g of solid CO2 evaporates into it.


The pressure of a particular mass of a gas can be calculated by the ideal gas equation:

PV = nRT

Where,

P = pressure

V = volume

n = number of moles

R = gas constant = 0.08206 L•atm/mol•K

T = temperature in Kelvin units


We can rearrange this formula for pressure.

P = nRTV
