Precision relates to instruments of measurement or scale . A scale measuring upto cm is less precise than an instrument measuring upto mm .

Third measurement is closest to the actual measurement that is 45.0 m , so it is most accurate measurement .

Explanation:
Hydrolysis is the chemical breakdown of a compound due to reaction with water. It may occur when acid or base is used as the catalyst.
The acid catalyzed hydrolysis of esters is the reverse of esterification. The alcohol and carboxylic acid that combined to form the ester are obtained in the process.
The acid catalyzed of butyl acetate is shown in the image attached.
