Hi, so to solve for this, we are to find the density of ammonia in grams per mile, given the temperature and then pressure.
00:12
So for this, we're going to use this equation.
00:15
Density is equivalent to pressure multiplied by the molar mass over r, the gas constant, and see the temperature.
00:23
So the molar mass of nh3, that ammonia is 14 .01 plus 3, multiple.
00:30
Applied by 1 .01, which is the atomic mass of hydrogen.
00:34
This should give us 17 .04 grams per mole.
00:39
So let's plug in the value here.
00:41
Pressure is 668, which is so...
