Answer to Question #193800 in General Chemistry for Lydia Wilton

Question

 A 25 cm³ sample of hydrochloric acid is sucked into a pipette and transferred into a 250 cm³ volumetric flask. The solution is made up to the mark.

 25 cm³ of the diluted acid is transferred into a conical flask using a pipette.

 A burette is used to neutralise the acid with 0.100 mol dm^-3 sodium hydroxide.

 

Hydrochloric acid reacts with sodium hydroxide according to the equation:

HCl_(aq) + NaOH_(aq)  NaCl_(aq) + H₂O_(l)

 

 The average titre of the sodium hydroxide solution was 30.00 cm³. Calculate the number of moles in the average titre

Answer 1

Number of moles in the average titre=18.54moles
