Question

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

Answer 1

Given data:

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)

Answer 2

Answer:

Digits in the measurement are significant figures are '6' and '7'.

Explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.

All non-zero numbers are always significant. For example: 604, 6.49 and 65.4 all have three significant figures.

All zero’s between integers are always significant. For example: 5005, 4.805 and 50.06 all have four significant figures.

All zero’s preceding the first integers are never significant. For example: 0.0058 has two significant figures.

All zero’s after the decimal point are always significant. For example: 4.500, 47.00 and 550.0 all have four significant figures.

Significant figures in measurement 0.0067 liter = 2

Digits in the measurement are significant figures are '6' and '7'.
