When you understand the etymologies of scientific terms, they make a lot of sense in relation to the term. The etymologies themselves often serve as a reasonably okay definition for the term.
Here's an example, many scientific terms have Greek or Latin etymologies. Take "archaeology" (for an example) Etymologically, it consists of two Greek words "archaeo" (old, ancient) and "logos" (a word, discourse, or study). Therefore, etymologically "archaeology" means "the study of old/ancient things."

If there are 0.2 M solutions of both acid and base, the concentrations of hydrogen and hydroxide ions will be equal at equivalence point.
The reaction of sulfuric acid and a basic solution BOH occurs as follows;
H2SO4(aq) + 2BOH(aq) -----> B2SO4(aq) + 2H2O(l)
In the question, we are told that that both the solution of the sulfuric acid and the basic solution are 0.2 M.
The point where all the hydrogen and hydroxide ions have reacted according to the stoichiometry of the reaction. If there is really equimolar amounts of acid and base, the concentration of hydrogen and hydroxide ions will be equal at equivalence point.

Answer:
0.0014 moles is present in 40cm³ of 0.035M of HCl solution
Explanation:
Molarity = 0.035M
V = 40.0mL
1mL = 1cm³
V = 40cm³
0.035 moles = 1000cm³
X moles is present in 40cm³
X = (40 * 0.035) / 1000
X = 0.0014moles
0.0014 moles is present in 40cm³ of solution
