So in this question, a compound is isolated from the range of lemons that is found to be 88 .14 % carbon and then 11 .86 % hydrating biomass.
00:12
The molar mass it is termed to be 1 to the 6 .26g per mole.
00:16
What is the molecular formula? so let's solve it.
00:23
So in order to find for the molecular formula, we first find our empirical formula.
00:27
Then in finding for empirical formula, we divide the mass percentage of each element by its molar mass.
00:33
So we have carbon with mass percentage of 88 .14 divided by its molar mass which is 12.
00:43
That will give us an answer of 7 .35.
00:52
And then we have hydrogen with mass percentage of 11 .86 with mass with a molar mass of 1.
01:03
That will give us an answer of 11 .86.
01:06
So we divide the values here by the least common value which is 7 .35.
01:11
So 7 .35 divided by 7 .35 will give us an answer of 1.
01:17
And then 11 .86 divided by 7 .35 will give us an answer of 1 .6.
01:28
So we multiply it by a common factor of 5.
01:34
So 1 times 5 will be equal to 5...
