4 moles
Explanation:
Given parameters:
number of moles of reacting NO = 24moles
Equation of the reaction:
4C₃H₆ + 6NO ⇒ 4C₃H₃N + H₂O + N₂
Solution:
The moles is synonymous the quantity of matter that contains the avogadro's number of particles.
To solve this problem, we must ensure that the given equation is balanced by simply inspecting.
The equation is balanced by inspection.
From the balanced equation;
6 moles of NO reacted to produce 1 mole of nitrogen gas
24 moles of NO will therefore produce = 4 moles

Explanation:
Given parameters:
Mass of sample = 235g
Molecular mass of sample = 128.1g
Empirical formula = CH₂O
Unknown:
Mass of each element in the sample = ?
Solution:
To solve this problem, we must know that the empirical formula of any compound is the simplest ratio of the atoms it contains. This is not the true formula of the compound.
Molecular formula = (Empirical formula)ₙ
Let us find the molecular mass of the sample;
CH₂O = 12 + 2(1) + 16 = 30g
128.1 = (30)n
n = 4
The molecular formula of the compound is; (CH₂O)₄ = C₄H₈O₄
Now to find the grams of each element in the sample;
Express the molecular mass of each element and that of the compound as a fraction and multiply with the given mass;
For C;
= 88.06g
H; = 14.68g
O: = 117.41g
