We have to describe how many significant figures should be reported for a mass of 25 g when it is weighed on a balance with a precision of 0.1 g.
Any measurement made by an instrument cannot be more precise than the maximum precision of the instrument.
Take example of a scale, that reads in cm units and the number of lines from 1 cm to 2 cm is 10. This means the precision of the scale is 0.1 cm so we cannot measure 0.23 cm using scale.
A sample that has a mass of about 25 g is weighed on a balance that has a precision of 0.1 g. How many significant figures should be reported for this measurement?
