A chemistry student needs 60.00 g of butanoic acid for an experiment. He has available 120. g of a 36.9% w/w solution of butanoi
2 answers:
<u>Answer:</u> There is no solution for the required amount of butanoic acid.
<u>Explanation:</u>
We are given:
Mass of butanoic acid needed = 60.00 grams
36.9 % w/w butanoic acid solution
This means that 36.9 grams of butanoic acid is present in 100 grams of solution
<u>Applying unitary method:</u>
If 36.9 grams of butanoic acid is present in 100 grams of solution
So, 60.00 grams of butanoic acid will be present in =
As, the given amount of solution is less than the required amount.
Hence, there is no solution for the required amount of butanoic acid.

Hello!
You would expect to observe 2 triplets in the ¹H NMR spectra for o-chlorotoluene.
Multiplicity observed in ¹H NMR spectra when the atom couples with a neighbor ¹H atom. The multiplicity is equal to N+1 where N is the number of neighbor atoms.
To observe a triplet, you'll need a molecule with 2 neighbor atoms. In o-chlorotoluene (shown in the figure), only protons C and D have 2 neighbor atoms (B and D; A and C, respectively), so you'll expect to see a 2 triplets.
Have a nice day!
