Question

1.) how many significant digits are in the measurement 0.005030 g? (1 point) 3 4 7 6

Explanation:

Step1: Identify non - zero digits

Non - zero digits are significant. In 0.005030, 5, 3 are non - zero digits.

Step2: Consider leading zeros

Leading zeros (zeros before non - zero digits) are not significant. So the three 0s before 5 are not significant.

Step3: Consider captive zeros

Captive zeros (zeros between non - zero digits) are significant. The 0 between 5 and 3 is significant.

Step4: Consider trailing zeros

Trailing zeros in a number with a decimal point are significant. The 0 after 3 is significant.

Answer:

B. 4
