E. the uncertainty is in the tenths place.
F. the mass measured on this balance is known exactly.
G. a mass that falls between 1 gram and 9 grams measured on this balance will always have 3 significant figures.
H. a mass that falls between 10 grams and 80 grams measured on this balance will always have 3 significant figures.
I. a mass that falls between 100 and 200 grams measured on this balance will have 5 significant figures.
