1
00:00:03.220 --> 00:00:06.750 A:middle L:90%
for split. We need to calculate the percent by
2
00:00:06.750 --> 00:00:12.099 A:middle L:90%
mass off nitrogen in the falling compounds for first in
3
00:00:12.099 --> 00:00:16.839 A:middle L:90%
its tree. Atomic weight. Nitrogen 14 hydrogen three
4
00:00:16.839 --> 00:00:20.829 A:middle L:90%
into one gives us total Molecular veda 17. So
5
00:00:20.829 --> 00:00:24.809 A:middle L:90%
person dates can be calculated as number off Factum Mile
6
00:00:24.809 --> 00:00:28.620 A:middle L:90%
. Deep light with the atomic weight divided by the
7
00:00:28.629 --> 00:00:34.130 A:middle L:90%
molecular formula. Wait in 200 Doing that, we
8
00:00:34.130 --> 00:00:38.759 A:middle L:90%
have the mask percentage off my Trojan in image three
9
00:00:38.770 --> 00:00:44.280 A:middle L:90%
as 82.2%. Using the same method, we need
10
00:00:44.280 --> 00:00:47.679 A:middle L:90%
to data mine for all off the compounds for second
11
00:00:47.679 --> 00:00:50.049 A:middle L:90%
compound. The mass percent ace turns out to be
12
00:00:50.640 --> 00:00:56.880 A:middle L:90%
34.9 for third compound. It is 21. This
13
00:00:56.880 --> 00:01:00.009 A:middle L:90%
is the second company. Here is the toad on
14
00:01:00.009 --> 00:01:03.480 A:middle L:90%
DDE. For the third compound, it is 21.2
15
00:01:03.939 --> 00:01:08.150 A:middle L:90%
. For the food compound, it is. Be
16
00:01:08.150 --> 00:01:15.859 A:middle L:90%
right, it's in. It's too two. Then
17
00:01:15.859 --> 00:01:21.219 A:middle L:90%
see Oh, sweet gives us to into 14 plus
18
00:01:21.219 --> 00:01:29.549 A:middle L:90%
four in tow. One plus 12 lust. 16
19
00:01:30.040 --> 00:01:32.650 A:middle L:90%
. So the total more legal form love it is
20
00:01:33.340 --> 00:01:41.530 A:middle L:90%
60.4 on the percentage nitrogen turns out to be to
21
00:01:41.540 --> 00:01:49.900 A:middle L:90%
into 14 divided by 60 Foreign deal for into 100
22
00:01:51.099 --> 00:01:56.939 A:middle L:90%
were to give those 46 point six blessing. No
23
00:01:56.950 --> 00:02:00.060 A:middle L:90%
. We have to rank the fertilizer in order off
24
00:02:00.060 --> 00:02:06.650 A:middle L:90%
decreasing percentage. So the highest percentage goes to in
25
00:02:06.650 --> 00:02:16.919 A:middle L:90%
its three. Then manage to go c o after
26
00:02:16.919 --> 00:02:23.030 A:middle L:90%
. Would it goes Toe image four. There's no
27
00:02:23.039 --> 00:02:30.849 A:middle L:90%
three further along. It goes to image. Four
28
00:02:30.740 --> 00:02:36.650 A:middle L:90%
Do. It's so for.
