Question

question 5 (1 point) how many significant figures (sig figs) are in the following number? 1.0 x 10^3 a 2 b 4 c 3 d 1

Explanation:

Step1: Recall significant - figures rule

In scientific notation \(a\times10^{n}\), the significant figures are determined by the coefficient \(a\).

Step2: Identify significant figures in coefficient

For the number \(1.0\times 10^{3}\), the coefficient is \(1.0\). Non - zero digits and zeros between non - zero digits are significant. Here, both 1 and 0 in 1.0 are significant. So there are 2 significant figures.
