We are looking at the decomposition of ammonium nitrate.
00:03
It produced nitrogen, oxygen, and water, and they're all in gas.
00:08
So all the information are summarized on your screen.
00:12
So first of all, we have 1 .55 kilogram of ammonium nitrate, and then we are looking at at 125 degrees celsius and 748 mm.
00:23
Okay, so we have to convert of the information that we have to lumber moles.
00:30
And also to corresponding unit that allow us to proceed with the calculations.
00:37
Okay, so first of all, we would like to find the number of moles of ammonium nitrate.
00:41
So we are going to take the mass divided by the motor mass, and then it will be equals to 90 .4 mole, correct to three significant figures.
00:51
And then we have to convert our temperature to calvin, so we're going to add the value by 273k, 273k, and last but not is we have to convert the pressure from millimeter mercury to h -tm.
01:06
So we are going to divide this number by 760 mm -mm and then we have 0 .984 atm.
01:16
Okay, so and then the next steps is we are going to find the mode ratio because we are interested in all of the gas.
01:24
So we are actually looking at the number of modes of all the gas instead of individual gas.
01:29
So we have 2 nitrogen, 1 oxygen, and 4 water...
