Answer:
D. when the number of moles of acid is exactly equal to the number of moles of base.
Explanation:
<em>Regarding options A. and E</em>., pKa and pKb would only be taken into consideration if the titrations were of <em>weak</em> acids and bases. However it is possible to have a titration of monoprotic acids and bases with strong acids and bases.
Another way of looking at the answer is identifying <em>which one best describes the equivalence point</em>.
The formula for density = mass/volume
So the units are gcm^3
So multiply by 1000 to get into grams - 1030500
Add units
1030500gcm^3
What's the question here???
