how many significant figures are in the measurement 0.002 ml?

2??

nope. 1. The number 2 is the only significant figure. The zeros are place holders only; i.e., they are they in order to set the decimal point.

okay, i get it, thank you!

Write down the significant figure of 0.002 m2

To determine the number of significant figures in a measurement, follow these steps:

Step 1: Identify all non-zero digits. In the measurement 0.002 mL, there is one non-zero digit, which is 2.

Step 2: Determine the zeros between non-zero digits. In this case, there are two zeros between the non-zero digit (2) and the decimal point.

Step 3: Count the zeros at the end of the number. There is one zero at the end of the number.

Step 4: Add up all the significant figures obtained from Steps 1 to 3. In this case, we have 1 (non-zero digit) + 2 (zeros between non-zero digits) + 1 (zero at the end) = 4 significant figures.

Therefore, the measurement 0.002 mL has 4 significant figures.
