Question

the correct number of significant figures in the number 0.027000 is:
○ 7
● 5
○ 6
○ ambiguous
possible points: 1

Explanation:

Step1: Recall significant figures rules

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

For the number \(0.027000\):

• The leading zeros (\(0.0\)) are not significant.
• The non - zero digits \(2\) and \(7\) are significant.
• The trailing zeros after the \(7\) (the three zeros: \(000\)) are significant because they are in a decimal number after the non - zero digits.

Step2: Count the significant figures

Count the significant digits: \(2\), \(7\), \(0\), \(0\), \(0\). So we have \(5\) significant figures.

Answer:

The correct option is the one with 5 (the option that was marked, likely the second option with the text "5" as per the given choices).
