2
1

Explanation:

Step1: Recall significant figure rules

Significant figures: Non - zero digits are significant. Zeros between non - zero digits are significant. Trailing zeros in a decimal number are significant.

Step2: Analyze the number 1.0060

• The digit 1 is non - zero, so it is significant.
• The zeros between 1 and 6 (the two zeros) are between non - zero digits, so they are significant.
• The digit 6 is non - zero, so it is significant.
• The trailing zero after the 6 (in the decimal part) is significant.

Counting these: 1, 0, 0, 6, 0. So there are 5 significant figures.

Answer:

5
