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.

Determine the number of significant figures for 28.6 grams?
Three - all nonzero numbers are significant.
How many significant figures does this number have?
In order to determine the number of significant figures in a number, you need to look at the non-zero digits and any zeros between them.
How do you use significant digits to determine how to report a sum or product of two measurements?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
How many significant figures does 20.2 have?
3 significant figures.
How many significant figures are in 50.000?
5 significant figures.
What is the number of significant figures in 546 km?
3 of them.
How do you determine how many significant figures to keep in an answer obtained by adding and subtracting?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
What is the rule you use to determine the number of significant figures in the results of addition and subtraction?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Determine the number of significant figures in each measurement 12.90s?
4 of them.
Determine the number of significant figures in 1.056 ml?
1.056ml has four significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
Determine the number of significant figures for 28.6 grams?
Three - all nonzero numbers are significant.
How do you tell what was the most significant figures?
Significant figures in a number are all the non-zero digits and zeros between them that are significant for the precision of the measurement. To determine the significant figures in a number, count all the non-zero digits and any zeros between them. Trailing zeros after a decimal point are also significant figures.
How many significant figures does this number have?
In order to determine the number of significant figures in a number, you need to look at the non-zero digits and any zeros between them.
How do you use significant digits to determine how to report a sum or product of two measurements?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Determine the number of significant figures of 2603000?
There are four significant figures in the number 2603000. Zeros at the end of a number are considered significant if they are to the right of the decimal point or if they are after a non-zero digit.
Determine the number of scientific figures in 56mL?
There are two significant figures in 56 mL. The first two digits are considered significant because they are non-zero digits. Zeros at the end of a number without a decimal point are not considered significant figures.
How much significant figures contains The measurement of 0.023 kg?
0.023kg has two significant figures. All non-zero digits are always significant. Leading zeroes, which only determine the decimal place, are never significant.
