Answer:
ratio=0.996m/s
Explanation:
; M= molecular weight of compound;
RMS speed is inversly proportional to the molecular weight hence compound having less molecular weight will have more rms speed value.

Answer is: B) titration.
Equivalence point is the point in which there is stoichiometrically equivalent amounts of acid and base.
Chemist can draw pH curve (graph showing the change in pH of a solution, which is being titrated) for titration and determine equivalence point.
The midpoint of a steep vertical section indicates the equivalence point
