Question

watch sig fig rules! (significant figures rules and examples) (8:44) then answer the following question. which of the following contains a \0\ that is not significant? hint: multiple answers may be correct. options: 102, 120., 12.0, 0.12, 120

Explanation:

Step1: Recall significant figure rules

Significant figure rules: 1. Non - zero digits are significant. 2. Zeros between non - zero digits are significant. 3. Zeros at the beginning of a decimal number (leading zeros) are not significant. 4. Zeros at the end of a number without a decimal point (trailing zeros in a whole number) may or may not be significant (usually considered not significant if there's no decimal), while zeros at the end of a number with a decimal point (trailing zeros in a decimal number) are significant.

Step2: Analyze each option

• Option 102: The zero is between 1 and 2, so it is significant.
• Option 120.: The decimal point after 120 indicates that the trailing zero is significant.
• Option 12.0: The trailing zero after the decimal is significant.
• Option 0.12: The leading zero before the decimal is not significant.
• Option 120: The trailing zero in this whole number (without a decimal) is not significant.

Answer:

0.12, 120
