Question

How many significant figures are contain in the following measurement?

1 . 3050m
a) 2
b) 3
c) 4
d) 5

Answer 1

The number of significant figures in a measurement is determined by the known digits plus one additional estimated or uncertain digit. In the measurement 1.3050, there are four significant figures.

Step-by-step explanation:

The number of significant figures in a measurement is determined by the digits that are known with certainty plus one additional digit that is estimated or uncertain. To determine the number of significant figures, we follow these rules:

1. All non-zero digits are significant. In the measurement 1.3050, there are four non-zero digits, so there are four significant figures.
2. Any zeros located in between significant figures in a number are also significant. In the measurement 1.3050, the zeros in between the non-zero digits are located in between significant figures, so they are significant. Therefore, there are four significant figures in the measurement.
