When the carbon dioxide sublims into the container, according to dalton's law of partial pressures, the pressure associated with carbon dioxide will be completely independent of any other gas that is present.
00:16
So, to calculate the pressure associated with carbon dioxide, we'll be using the ideal gas law, where it will be equal to the moles of carbon dioxide, multiplied by r, multiplied by the kelvin temperature, divided by the volume in liters.
00:34
The moles can be calculated by taking the mass at 5 .50 grams and converting it into moles by dividing by the molar mass.
00:43
One mole, carbon dioxide, is 44 .01 grams.
00:51
We'll then multiply that by r, 0 .0 .0826, liter atmospheres per kelvin mole.
01:03
And then the kelvin temperature, the temperature is 24 degrees celsius.
01:08
We assume it stays at 24 degrees celsius.
01:11
It probably won't when it sublimes because carbon dioxide as dry ice is cold, but we'll assume that...
