A student 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

Correct answer

3

Step-by-step solution

Average aligned & = 25.2+25.25+25.0 3 = 75.45 3 & =25.15=25.2 ~mL aligned Number of significant figure is 3 . Basics in chemistry Rule application III (Difficulty level is high because of shear ignorance of such topics)
