Karen massed an object 3 times using the same equal arm balance and gram massed. Her results were 18.324 g 18.308 g and 18.342 g. How could she best report the mass of the object

Respuesta :

To best report the mass of the object, she could just find the average for the three masses she measured.
average = total masses / number of readings

Total masses = 18.324 + 18.308 + 18.342 = 54.974 grams
number of readings = 3 readings

Therefore:
average mass of the object = 54.974 / 3 = 18.32466667 grams
