A student performs a titration with different burettes and find titre values of `25.2 mL, 25.25 mL and 25.0 mL`. What is the average titre value based upon rounded off principle ?

Text Solution

Verified by Experts

Average titre value `= ((25.2+25.25+25.0))/(3)mL=25.15mL`
The maximum number of significant figures to be reported is three (3). This means that the last digit 5 has to be dropped and the correct answer is 25.2 mL based on rule-3.
