Question

which measured value contains a zero that is not a significant figure?
○8.08
○0.984
○65.0
○40.00
○all of the zeroes are significant figures in the measured values above.

Explanation:

Step1: Recall significant figure rules for zeros

Zeros between non - zero digits are significant. Zeros at the end of a number after the decimal point are significant. Leading zeros (zeros before the first non - zero digit) are not significant.

Step2: Analyze each option

• For \(8.08\): The zero is between two non - zero digits (8 and 8), so it is significant.
• For \(0.984\): The zero is a leading zero (before the non - zero digit 9), so it is not significant.
• For \(65.0\): The zero is at the end of the number after the decimal point, so it is significant.
• For \(40.00\): The zeros after the decimal point and the zero between 4 and the decimal - related zeros are significant (the zero between 4 and the first decimal zero is between non - zero digits in terms of significant figure consideration for this number's structure, and the trailing zeros after decimal are significant).

Answer:

B. 0.984
