Hi, so to solve for this, we are to calculate the pressure of the gas sample based on the given information here.
00:08
So we will use the ideal gas equation pv is equivalent to nrt, where p is the pressure in terms of atm, v is the volume in terms of liters, n is the number of moles, r is the ideal gas constant, and t is the temperature in terms of kelvin.
00:24
And our unknown here is pressure.
00:27
So rearranging this equation, we'll have nrt over the volume.
00:32
So let's plug in the information that we have.
00:34
The number of moles is 1 .33 moles.
00:38
R is equivalent to 0 .0821 liters atm per mole kelvin.
00:45
So this is the volume of r, and this could be easily looked up in standard reference materials, but it would be better if you could just memorize this constant.

Now the temperature is 22 degrees celsius...
