1
00:00:00.790 --> 00:00:04.889 A:middle L:90%
we have all South nitrogen is 40.45 or several fashion
2
00:00:04.889 --> 00:00:07.200 A:middle L:90%
by mass. So what would be the end people
3
00:00:07.200 --> 00:00:10.900 A:middle L:90%
for murder And also Eve the, um, the
4
00:00:10.900 --> 00:00:13.619 A:middle L:90%
masses. 90%. Last five grand, Perma.
5
00:00:13.619 --> 00:00:15.390 A:middle L:90%
What would be the market of formula? So we
6
00:00:15.390 --> 00:00:18.250 A:middle L:90%
first staff party, what would be the chemical formula
7
00:00:18.739 --> 00:00:20.219 A:middle L:90%
? So, uh, people were looking at the
8
00:00:20.219 --> 00:00:22.780 A:middle L:90%
masters and thinks we can assume that we have one
9
00:00:22.780 --> 00:00:26.679 A:middle L:90%
Joe Graham off our, um, all silent nitrogen
10
00:00:26.890 --> 00:00:31.539 A:middle L:90%
. So therefore, we have 30 44 5 graham
11
00:00:31.550 --> 00:00:34.289 A:middle L:90%
off nine Children. Okay, so we just need
12
00:00:34.289 --> 00:00:36.850 A:middle L:90%
to convert back to lumber. Most of us.
13
00:00:38.039 --> 00:00:41.850 A:middle L:90%
Um okay. So, uh, okay. Before
14
00:00:41.850 --> 00:00:44.320 A:middle L:90%
we doing that? Ah, we also have oxygen
15
00:00:44.390 --> 00:00:46.590 A:middle L:90%
. That's what we're oxide elf. Naturally. So
16
00:00:46.810 --> 00:00:49.479 A:middle L:90%
we can also calculate the mass off. Oxygen therapy
17
00:00:49.479 --> 00:00:52.640 A:middle L:90%
equals the 100 people. Were someone your crime minus
18
00:00:52.640 --> 00:00:57.859 A:middle L:90%
13 44 5 grams were 65.55 grams off oxygen.
19
00:00:58.130 --> 00:01:00.299 A:middle L:90%
So we're gonna work it to number almost full for
20
00:01:00.299 --> 00:01:03.409 A:middle L:90%
the number most off oxygen. There will be,
21
00:01:03.409 --> 00:01:12.409 A:middle L:90%
Ah, 22.17 Felipe, mo. And ever oxygen
22
00:01:12.409 --> 00:01:19.739 A:middle L:90%
you will be, um, 4.347 more. All
23
00:01:19.739 --> 00:01:22.409 A:middle L:90%
right, So you're the father of foreigner. We're
24
00:01:22.409 --> 00:01:23.390 A:middle L:90%
going to set up the way. Show between the
25
00:01:23.390 --> 00:01:26.390 A:middle L:90%
number more for nitrogen and so and also the oxygen
26
00:01:26.390 --> 00:01:30.109 A:middle L:90%
and everyone's simplify it. So we're going to divide
27
00:01:30.109 --> 00:01:33.420 A:middle L:90%
the whole everything about the smallest thumper coupon. 1/7
28
00:01:33.420 --> 00:01:34.709 A:middle L:90%
. We we should be able to find that away
29
00:01:34.709 --> 00:01:40.299 A:middle L:90%
show is what you earn wants you to nitrogen oxygen
30
00:01:40.299 --> 00:01:42.920 A:middle L:90%
. So we have an over two for the empirical
31
00:01:42.920 --> 00:01:46.579 A:middle L:90%
formula. Okay, We can, uh, move
32
00:01:46.579 --> 00:01:48.459 A:middle L:90%
on. OK, See, we have no the
33
00:01:48.459 --> 00:01:52.060 A:middle L:90%
empirical farmers. And what you and these chemical formula
34
00:01:52.060 --> 00:01:56.209 A:middle L:90%
We'll have a molar mass. Um 14. 16
35
00:01:56.209 --> 00:02:00.329 A:middle L:90%
times 2 46 uh, gram for move. So
36
00:02:00.329 --> 00:02:04.629 A:middle L:90%
we're going to take out Toto with a mass Ah
37
00:02:04.640 --> 00:02:07.340 A:middle L:90%
, divided by our empirical for former member of the
38
00:02:07.340 --> 00:02:10.680 A:middle L:90%
Mass. So, um, but you can you
39
00:02:10.680 --> 00:02:14.909 A:middle L:90%
can see the estate Ruby person minus five gram.
40
00:02:15.180 --> 00:02:16.530 A:middle L:90%
So from here, we can separate two such a
41
00:02:16.530 --> 00:02:21.729 A:middle L:90%
scenario so we can have ah, 95. And
42
00:02:21.729 --> 00:02:24.530 A:middle L:90%
also we got 1/2 85 because his nineties, the
43
00:02:24.530 --> 00:02:28.039 A:middle L:90%
center and the undefined. And if I will find
44
00:02:28.039 --> 00:02:30.879 A:middle L:90%
out the bank free between the lumber. Okay,
45
00:02:30.879 --> 00:02:32.889 A:middle L:90%
I assume we have 95. Ah, we're doing
46
00:02:32.889 --> 00:02:36.500 A:middle L:90%
had 90 find you want by 46. Ah,
47
00:02:36.500 --> 00:02:38.520 A:middle L:90%
we will find that the mother of all was perfect
48
00:02:38.520 --> 00:02:39.750 A:middle L:90%
. I have learned to upon cereal six again is
49
00:02:39.750 --> 00:02:44.449 A:middle L:90%
what we have learned to every 85 there were 46
50
00:02:44.840 --> 00:02:46.229 A:middle L:90%
. We have them live or roughly around. Um
51
00:02:46.520 --> 00:02:51.389 A:middle L:90%
, 1.4, um five. Also roughly around,
52
00:02:51.389 --> 00:02:53.319 A:middle L:90%
too. If you think the center lumber 90 divide
53
00:02:53.330 --> 00:02:57.449 A:middle L:90%
our forces. We also have 40 around one point
54
00:02:57.449 --> 00:03:00.580 A:middle L:90%
now. Six. Also remember the two. So
55
00:03:00.580 --> 00:03:01.719 A:middle L:90%
, uh, from from the upper boundary and their
56
00:03:01.719 --> 00:03:07.340 A:middle L:90%
center ah will amass ethicists corresponding 90 years 95.
57
00:03:07.349 --> 00:03:08.870 A:middle L:90%
And this knife ugly five. We can see that
58
00:03:08.870 --> 00:03:12.629 A:middle L:90%
the multiple also is ah, free around too.
59
00:03:12.860 --> 00:03:15.349 A:middle L:90%
So we can know that the mogul formula should be
60
00:03:16.139 --> 00:03:19.969 A:middle L:90%
And 204 with the mobile by two. We just
61
00:03:19.969 --> 00:03:22.650 A:middle L:90%
multiply that to, um, hour
