A57299 SolutionThe mass for first trial 1st mass measuremen

Solution

The mass for first trial

= (1st mass measurement + 2nd mass measurement + 3rd mass measurement) /3

=( 57.300 + 57.297 + 57.297)/3

= 57.298 g

The mass for second trial

= (1st mass measurement + 2nd mass measurement +  3rd mass measurement) /3

=( 57.300 + 57.299 + 57.298)/3

= 57.299 g

The mass for third trial

= (1st mass measurement + 2nd mass measurement +  3rd mass measurement) /3

=( 57.300 + 57.295 + 57.296)/3

= 57.297 g
