00:01 All right, so for this question, we're trying to fill in the blanks in the table.

00:05 So we're told us an ideal gas.

00:07 So for this problem, we are going to use the ideal gas law.

00:13 So the ideal gas equation is pressure times volume equals n the moles times r the gas constant, times t the temperature.

00:28 And then the other value we need that's not included is r, which equals 0 .08 .0 .7.

00:34 6 liters per atmospheres over kelvin times moles.

00:40 Now, pay attention to the units on the gas constant because that's going to tell you what the units of each of these different parts need to be in order for them to cancel out.

00:49 So volume always has to be in liters, pressure has to be in atmospheres, temperature has to be in kelvin, and then moles are in moles.

00:56 So let's start with the first row where we are solving for temperature.

01:06 So we just start filling in our values into the equation.

01:10 So our pressure, two atmospheres times our volume 1 .00 liters equals n our moles times the gas constant, liters atmospheres over kelvin times moles, times the temperature.

01:38 And then you just solve for t.

01:43 So you'll take two atmosphere times one liter.

01:48 Divided by 0 .5 moles, divided by the gas constant to get t by itself, and t should equal 48 .7 kelvin's.

02:03 So that's going to be your first box.

02:06 Then we're going to do the same thing for the second row, and we're trying to solve for n.

02:15 So we take our pressure, 0 .3 atmospheres, times our volume of 0 .250 liters, is equal to end the moles, which is what we're trying to find, times the gas constant.

02:36 Point 08026.

02:43 Oh, i think i wrote it at the wrong at the bottom down here.

02:50 08 -26.

02:54 There you go.

02:56 All right, so times the gas constant, which is liters times atmospheres over kelvin times moles, times the temperature, but the temperature has to be in kelvin, and it's given to us in degrees celsius...
