Question

Which of the following measurements has 2 significant figures?
O 0.001 cm
11.0 cm
O 100 cm
O 100 cm

Answer 1

Answer:

none

Explanation:

0.001 cm ... 1 significant figure (none of the decimal zeros before 1 count)

11.0 cm ... 3 significant figures (the decimal zero NOT followed by a non-zero number count)

100 cm ... 1 significant figure (two zeros do NOT count)

100. cm ... 3 significant figures (because there is a decimal point, the two zeros count)
