The volume of solution in a test tube is measured to be 0.0067 liter. Which digits in the measurement are significant figures?

Given dа ta:

Volume of solution measured = 0.0067 L

To determine:

The number of significant figures

Explanation:

Significant figures are the number of digits that accurately describe a measured value.

As per the rules:

All non-zero digits are significant

Leading zero's i. e. the zero's after a decimal which comes before a non-zero digit are not significant

Hence in the given value 0.0067, there are 2 significant figures (6 &7)
