A student of performs a titration with different burettes and finds titre values of `25.2 mL`, `25.25 mL`, and `25.0 mL`. The number of significant figures in the average titre value is …..

Text Solution

Verified by Experts

The correct Answer is:

Because, least precise data contains `3` significant figures.
Average value `=(25.2+25.25+25.0)/(3)=25.25 rArr25.2`
