A 30.00 mL sample of vinegar is titrated with 0.4190 M NaOH(aq). If the titration requires 27.83 mL of NaOH(aq), what is the concentration of acetic acid in the vinegar?

0.389 M

Explanation:

Using the formula; CaVa = CbVb

Where;

Ca = concentration of acid

Cb = concentration of base

Va = volume of acid

Vb = volume of base

Based on the provided information in the question, Va = 30mL, Ca=?, Vb = 27.83mL, Cb = 0.4190 M

Hence, CaVa = CbVb

Ca = CbVb/Va

Ca = 0.4190 × 27.83 ÷ 30

Ca = 11.6607 ÷ 30

Ca = 0.3886

Ca = 0.389 M

Therefore, the concentration of acetic acid in the vinegar is 0.389 M

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
