00:00:03.839 --> 00:00:07.160 A:middle L:90%
this question is exactly same as the previous potion where
2
00:00:07.160 --> 00:00:09.949 A:middle L:90%
we are given with empirical formula. See for EJ
3
00:00:09.949 --> 00:00:13.839 A:middle L:90%
night. We can calculate the molar mass carbon corresponds
4
00:00:13.839 --> 00:00:18.260 A:middle L:90%
to 12 and hydrogen corresponds to nine on her.
5
00:00:18.280 --> 00:00:22.539 A:middle L:90%
Erosion corresponds to one the total Mullah Omar's turns out
6
00:00:22.539 --> 00:00:27.440 A:middle L:90%
Toby 114.2 grams. We can determine the molecular formula
7
00:00:27.449 --> 00:00:29.850 A:middle L:90%
, which is equal to empirical formula in tow.
8
00:00:29.850 --> 00:00:33.560 A:middle L:90%
And we're n stands for number off compounds. We
9
00:00:33.560 --> 00:00:36.109 A:middle L:90%
can rearrange this formula in tow. The given form
10
00:00:36.119 --> 00:00:40.950 A:middle L:90%
. Let's market as number one, substituting in,
11
00:00:41.439 --> 00:00:44.820 A:middle L:90%
substituting in the values into the empirical formula. Toe
12
00:00:44.829 --> 00:00:46.950 A:middle L:90%
to toe mine end that is number of compounds,
13
00:00:47.439 --> 00:00:50.630 A:middle L:90%
it turns out, an equals two. Hence the
14
00:00:50.630 --> 00:00:55.630 A:middle L:90%
monocle formalize multiplied with to giving us C A F
15
00:00:55.649 --> 00:00:58.289 A:middle L:90%
18. Same is to be done for partner will
16
00:00:58.289 --> 00:01:06.400 A:middle L:90%
be them. Vehicle formula off Cecile is 284.77 The
17
00:01:06.400 --> 00:01:08.439 A:middle L:90%
value off end turns out to be six. We
18
00:01:08.439 --> 00:01:14.030 A:middle L:90%
multiply CCL with six, giving us the monocle farm
19
00:01:14.030 --> 00:01:19.159 A:middle L:90%
. Last see six see in six for party.
20
00:01:19.170 --> 00:01:23.489 A:middle L:90%
The empirical formula is C three edge to and where
21
00:01:23.489 --> 00:01:30.030 A:middle L:90%
the more legal Thomas is. 312.29 grams. The
22
00:01:30.040 --> 00:01:33.819 A:middle L:90%
end that is number of compound in this case turns
23
00:01:33.819 --> 00:01:36.540 A:middle L:90%
out to be six, multiplying the more legal form
24
00:01:36.540 --> 00:01:41.650 A:middle L:90%
Love with six giving US C 18 vegetable and six
25
--> A:middle L:90%
.
