To find out how many molecules you have, you need to multiply the number of moles with Avogadros constant: 2.50 * 6.022 * 10²³ = 1.5055 * 10^24.
Answer:
<h2>acetyl chloride > acetic anhydride > methyl acetate > acetamide</h2>
Explanation:
Such kind of substitution reaction in which nucleophiles and the acyl compound interact is known as nucleophilic acyl substitution reaction. In this reaction, the interaction between carbonyl compounds and the nucleophile takes place by addition reaction. The reactivity of the acyl compound is based on the condition of the leaving group that is related to the acidity of the compounds. So the decreasing order of reactivity of the acyl compounds is, acetyl chloride > acetic anhydride > methyl acetate > acetamide.

<span>There
are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. We calculate as follows:
</span>
2.5 M HCl = 2.5 mol HCl / L soln
0.306 mol HCl / 2.5 mol HCl/L son = 0.1224 L soln needed
M1V1 = M2V2
18 M(V1) = 2.5 M(0.1224 L)
V1 = 0.017 L of the 18 M solution
The two lines show that these are the only two lines that do not cause energy transition in the sodium atom. Option D
<h3>What are the two lines in the spectrum of sodium atom?</h3>
The spectrum of the sodium atom appears as a doublet. This implies that there are two lines in the spectrum and they appear as bright yellow lines that are not spaced apart in the spectrum.
The two bright yellow vertical lines in the spectrum shows that these are the only two lines that do not cause energy transition in the sodium atom.
