Electronegativity is the measure for an atom to acquire an electron to form a bonding pair. Lithium wants to lose its outermost electron and does not want to acquire any more electrons therefore it would have the lowest EN.

C₁₄H₂₂N₄O₈
Explanation:
To find the molecular weight of the compound C₁₄H₂₂N₄O₈ we simply sum that atomic masses of the given elements in the compound.
The empirical weight is determined by using the simplest ratio of the elements involved in the compound;
Molecular weight of C₁₄H₂₂N₄O₈;
atomic mass of C = 12g/mol
H = 1g/mol
N = 14g/mol
O = 16g/mol
Molecular weight = 14(12) + 22(1) + 4(14) + 8(16)
= 168 + 22 + 56 + 128
= 374u
Empirical weight:
Empirical formula:
C₁₄ H₂₂ N₄ O₈
14 : 22 : 4 : 8
divide by 2:
7 : 11 : 2 : 4
empirical formula C₇H₁₁N₂O₄
empirical weight = = = 187u
The molecular formula is the actual combination of atoms in a compound. so the molecular formula of the compound is C₁₄H₂₂N₄O₈

<u>Answer:</u>
<em>The number of moles of HCl actually present is 0.000988</em>
<u>Explanation:</u>
<em>The balanced chemical equation of the given reaction is </em>
Here one mole of HCl reacts with one mole of NaOH to form one mole of NaCl and one mole of water. Here the molarity of HCl is given as 0.026M.
<em>molarity of NaOH is 0.032M
</em>
molarity is the number of moles per unit volume of solution.
we have to calculate the number of moles in 36 mL of HCl.
<em>38 mL=36/1000=0.038L
</em>
<em>the number of moles in 38 mL of HCl is given by
</em>
<em>no of moles =</em>
