1. An object was carefully weighed on three different balances. Each balance was zeroed before weighing. The masses were: 10.35 g. 10.355 g, and 10.30 g. Calculate the average value
of these measurements. (Please show all work and pay attention to significant figure rules.)

10.335

Explanation:

An object was carefully weighed on three different balances

Each of these balances were zeroed before weighing

The masses that were weighed are as follows

10.35 g , 10.355 g, 10.30 g

Therefore the average value of these measurements can be calculated as follows

The total number of mass is 3

= 10.30 + 10.355 + 10.30/3

= 31,005/3

= 10.335

Hence the average value of these measurements is 10.335

the correct answer is:
