Chemistry: The Molecular Science
A set of measurements is limited by the precision of the least-sensitive instrument
used in the experiments. The mass is known to five significant figures, but there
are only three significant figures in the volume. Thus only three significant figures

To indicate the precision of a measured number (or result of calculations on
measured numbers), we often use the concept of significant figures. Significant
figures are those digits in a measured number (or in the result of a calculation
with ...

The number 2.34 g has only three significant figures and implies the 4 is
uncertain, when in fact the balance reading indicated the 4 is certain. In the case

Barron's SAT Subject Test in Chemistry
For instance, if an instrument that measures to the nearest mile is used, the
number 3,000 miles has four significant figures. If, however, the instrument in
question records miles to the nearest thousands, there is only one significant
figure.

Significant figures in the measured value of a physical quantity tell the number of
digits in which we have confidence. Larger the number of significant figures
obtained in a measurement, greater is the accuracy of the measurement. The
