Question

indicate how many significant figures there are in each of the following measured values. 5.000 x 10^2
a. 5
b. 3
c. 4
d. 2
e. 1

Explanation:

Step1: Recall significant - figures rule

Non - zero digits and zeros between non - zero digits are significant. In scientific notation \(a\times10^{n}\), the significant figures are in the coefficient \(a\).

Step2: Identify significant figures in \(5.000\times 10^{2}\)

The coefficient is \(5.000\). Here, 5 is a non - zero digit and the three zeros between non - zero digits are also significant. So, there are 4 significant figures.

Answer:

C. 4
