Quiz - Significant Figures | Chemistry and the Scientific Method

In the measurement 43.0 cm, all digits (4, 3, and 0) are considered significant because they contribute to the precision of the measurement. Therefore, there are three significant figures.

In the measurement 0.00560 g, all digits after 5 (5, 6, and 0) are considered significant because they contribute to the precision of the measurement. Therefore, there are three significant figures.

In the measurement 102,400 mL, all non-zero digits (1, 2, 4) are considered significant, as well as the zeros between them. Therefore, there are four significant figures.

In the measurement 7.8030 g, all non-zero digits (7, 8, 3) are considered significant, as well as the zero between them and the final zero after the last non-zero digit. Therefore, there are five significant figures.

In scientific notation, all digits in the coefficient are considered significant. Therefore, in 5.000×10⁷, all digits (5, 0, 0, 0) are significant, resulting in four significant figures.

In the measurement 0.095, all digits after 9 (9, 5) are considered significant because they contribute to the precision of the measurement. Therefore, there are two significant figures.
