Answer:
Explanation:
We will need a balanced equation with moles, so let's gather all the information in one place.
CH₃C₆H₄NH₂·HCl + (CH₃CO)₂O ⟶ CH₃C₆H₄NHCOCH₃ + junk
V/mL: 70.
c/mol·L⁻¹: 0.167
For simplicity in writing , let's call p-toluidine hydrochloride A and N-acetyl-<em>p</em>-toluidine B.
The equation is then
A + Ac₂O ⟶ B + junk
1. Moles of A
2. Moles of B
The molar ratio is 1 mol B:1 mol A
Moles of B = moles of A = 12 mmol = 0.012 mol

Answer: O 10.1 is your answer! Please mark me as brainlyest!?
Percent composition is the quantity or number of parts of a component contained in 100 parts of the total.
Given the the total is 100 g, the reported quantities for each component are the same percent.
Then, the percent composition of each as part of the entire sweet peas is:
Carb: 14.5%
Sugar: 5.7%
Diet. fiber: 5.1%
Prot: 5.4%
Fat: 0.4%
The rest to make the 100% is supposed to be water.
You could also find the percent composition in dry basis, which is done in this way (this is not what the question asks but it is good to know it).
Total components without water: 14.5 + 5.7 + 5.1 + 5.4 + 0.4 = 31.1 grams
Now divide each content by the total (31.1) and multiply by 100.
I will do one example:
Carbs: [14.5 / 31.1 ] * 100 = 46.6%
