Question

select the significant figures in the measurement. 0.0090 kilograms

Explanation:

Step1: Recall significant - figures rules

Non - zero digits are always significant. Leading zeros (zeros before non - zero digits) are not significant. Trailing zeros (zeros after non - zero digits) are significant if there is a decimal point.

Step2: Analyze the number 0.0090

The leading zeros (the three zeros before 9) are not significant. The non - zero digit 9 is significant. The trailing zero after 9 is significant because there is a decimal point.

Answer:

9, 0
