The moles of NaOH used in the titration would be 0.00177 moles while the molarity of the vinegar will be 0.885 M
<h3>Titration calculation</h3>
Recall that: mole = molarity x volume
In this case, the molarity of the NaOH= 0.1 M
Volume of NaOH = 17.7 - 0.0 = 17.7 mL
Mole of NaOH used = 0.1 x 17.7/1000 = 0.00177 moles.
Since NaOH and vinegar have 1:1 mole ratio, the mole of vinegar will also be 0.00177 moles.
Molarity of vinegar = mole/volume = 0.00177/0.002 = 0.885 M

Answer:
pKa = 9
Explanation:
In this case, we have to remember the meaning of "p". When we use "p" in any calculation we have to apply the minus ten based logarithm, so:
For example, when we use the "pH" value. We have to apply the minus ten based logarithm of the concentration of the hydronium ion:
![pH~=~-Log[H^+]](https://tex.z-dn.net/?f=pH~%3D~-Log%5BH%5E%2B%5D)
So, if we have wanted to calculate the pKa value. We have to apply the minus ten based logarithm of the Ka value, so:
Now we can plug the value into the equation:
<u>The pKa value is 9.</u>

If you want to answer this question, all you have to do is take a look at the periodic table. <span>An element might substitute for another element if it is from the same family/column on the periodic table.
So, these are the atoms which might substitute for one another:
1. Si = C.C
2. K = A. Na
3. Nb = B. V
4. Cu = D. Ag
5. P = F. As
6. Mg = E. Ca
