How many significant figures in 0.0103?
Well, honey, in 0.0103, there are three significant figures. The zeros at the beginning are just placeholders, so they don't count. So, you're left with the 1, the 0, and the 3 strutting their stuff as the significant figures in this number.
If there are two zeros on the end of a number are they both significant?
The number of significant figures depends on the the errors of measurement, the uncertainty of reported values, and the significant figures of table values. Ending zeros are only significant if necessary. For example, suppose I want the number of meters in a kilometer to four significant figures. In scientific notation this would be 1.000 * 103. In regular notation, it would be 1000. The period at the end is not for the end of the sentence, but rather to signify that all included digits represent significant digits with regard to accuracy.
