How are significant figures determined when measurements are used in calculations?
The rules for identifying significant figures when writing or interpreting numbers are as follows:
All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5).
Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3.
Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2.
Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.

In adding the measurements 11.074m 18.2m and 16.943m what should be the number of significant figures in the result?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
What do significant figures tell about an instrument?
They tell you what level of precision you can expect from measurements that are made using that instrument.
How do you use significant digits when repeating the results of calculations involving measurements?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
What determines the number of significant figures in density calculations?
The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
Why when you make measurements should the answer only have the same number of significant figures as the measurement with the fewest significant figures?
When performing calculations with measurements, it is important to maintain the same level of precision as the least precise measurement to avoid introducing false accuracy. Using more significant figures in the final result than what was present in the original measurements can lead to misleadingly precise results. Therefore, limiting the number of significant figures in the final answer prevents suggesting a level of precision that was not actually present in the original data.
