Question

Consider the following:
a) 0.0025
b) 500.0
c) 2.0034
Number of significant figures in A, B and C respectively are

• A. 5, 4, 4
• B. 2, 4, 2
• C. 4, 3, 2
• D. 2, 4, 5

Hint:

To easily identify significant figures, try writing the number in scientific notation. For example, \( 0.0025 \) becomes \( 2.5 \times 10^{-3} \) (2 digits), and \( 500.0 \) becomes \( 5.000 \times 10^2 \) (4 digits). The digits in the coefficient are always the significant ones!

Answer 1

The Correct Option is D
