Question

question 14
how many significant figures are in the number 0.020300?

Explanation:

Step1: Determine significant figure rules

Non - zero digits are significant. Zeros between non - zero digits are significant. Trailing zeros in a decimal number are significant. Leading zeros (zeros before the first non - zero digit) are not significant.

Step2: Analyze the number \(0.020300\)

The first non - zero digit is \(2\). The zeros between \(2\) and \(3\) (\(0\) in \(203\)) is significant. The trailing zeros (\(00\) after \(3\)) are significant. The leading zeros (\(0.0\)) are not significant.
So the significant digits are \(2\), \(0\), \(3\), \(0\), \(0\)
