Hi, so to solve for this, we're calculating the volume and we have the temperature and pressure and we also have the mass of carbon dioxide or dry ice.
00:15
So that means we will use the ideal gas equation pv is equivalent to nrt.
00:21
So solving for the volume, we'll have nrt over the pressure.
00:26
So n is the number of moles, r is the gas constant, and t is the temperature, p is the pressure.
00:32
And how do we solve for the number of moles? if we have 28 .8, this is grams of co2.
00:37
Since we know that all of the carbon dioxide ends up in the balloon, convert grams to moles by dividing the molar mass of co2, that's 44 .01 grams.
00:50
And we have here moles.
00:51
Now the gas constant is 0 .0821 liters, 80 ampere mole kelvin.
00:58
And then the temperature is 22 degrees celsius...
