Answering Numerical Questions That Check Significant Figures
| Rule | Example | Significant Figures |
|---|---|---|
| Every non-zero digit is significant. | 1234 | 4 |
| Zeros in between non-zero digits are significant. | 101.001 41003 | 6 5 |
| Zeros at the end of the answer when no decimal point is specified are not significant. | 500 13000 140e-001 | 1 2 2 |
How many significant figures are in the number 300?
3 sig
Example: 300 has 1 sig. fig., 25400 has 3 sig. figs. b) If there is a decimal, the zeros ARE significant.
How many significant figures does zero apples?
1 sig fig
The zero in the ones place does not count as a significant figure as it is a leading zero. Because of this, we only have 1 sig fig.
How do you determine the number of significant figures?
The number of significant figures is determined by starting with the leftmost non-zero digit. The leftmost non-zero digit is sometimes called the most significant digit or the most significant figure.
How can you tell how many significant figures are in a number?
There are three rules on determining how many significant figures are in a number: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.
What is the appropriate number of significant figures?
As a result, you can only claim two significant digits in your answer. In other words, the “appropriate” number of significant digits is two, and you would report (in your physics lab report, for instance) that the volume of the block is 42 cubic inches, approximately.
How many significant figures are there in an exact number?
Certain types of numbers are considered “exact.” For example, there are exactly 16 ounces in one pound. The number 16 would have as many significant figures as needed.
