Question
Two gold pieces weigh 20.15 g and 20.17 g. What is the difference in the masses of the pieces to correct significant figures?
Solution
Mass of first piece = 20.15 g
MAss of second piece = 20.17 g
Therefore,
MAss of second piece = 20.17 g
Therefore,
Difference in the masses of two pieces is,
m = (20.17 - 20.15) g
= 0.02 g
Since the masses of pieces are known upto second decimal place of gm and difference is also upto second decimal place, hence the difference in the masses is 0.02 g.
m = (20.17 - 20.15) g= 0.02 g
Since the masses of pieces are known upto second decimal place of gm and difference is also upto second decimal place, hence the difference in the masses is 0.02 g.
