Succinic acid has the formula (CH2)-(COOH)2 and reacts with dilute sodium hydroxide as follows:
(CH)-(COOH)2 + 2NaOH → (CH2)-(COONa)2 + 2H2O
2.0 g of succinic acid were dissolved in water and the solution made up to
250 cm. This solution was placed in a burette and 18.4 cme was required to
neutralise 25 cms of 0.1 moldm3 NaOH. Deduce the molecular formula of
the acid and hence the value of n.

Ascientist wants to know how individual lions within a pride interact with each other in their own environment. to do this, the scientist sedates and tags all of the lions within a pride. then, he places several remotely-controlled video cameras near the lions' den and performs an observational field study. he collects continuous video footage over the span of one year, analyzes the video, and then forms conclusions based on his observations.
