Respuesta :
8820 and 0.0882 have three sig figs
When a number has zeros in it I struggled a lot to determine if it what a sig fig or not. This is how I remember it:
If a zero is a sandwich between normal numbers it IS a sig fig
Zero's after the decimal ARE sig figs
***IMPORTANT! There is an exception to this one which I'll talk about next :)
Leading zeros (I believe that is what they are called) are NOT sig figs. This would be like the zeros in the following numbers:
0.2
0.03
0.000000000000000000006
If there are zeros after normal numbers and there is NO DECIMAL it is NOT a sig fig. This would be like the zeros in the following numbers:
630
3, 000
536, 329,600,000
Take a look at the other numbers:
0.8820 <<<This has 4 sig. figs.
882.0 <<<This has 4 sig. figs.
***Remember that if there is a pure decimal the zero in front of the decimal is NOT a sig fig and just a place holder. It isn't necessary and can always be taken away
Hope this made sense and helped!!!
The 8820 m and 0.0882 m have three significant figures
What are the rule to determines significant figures?
There are rules are to be applied to determine the significant figures in a suitable quantity.
- All non-zero digits are significant.
Example : 23 cm ,2.3 cm , and 0. 23 cm all have two significant figures.
- The zeros present to the of the first non-zero digit in the number are not considered as significant figures
Example: 0.033 has two significant figures and 0.00172 has three significant figures.
- Zeros present between the two non-zero digits are significant.
Example: 6601 has four significant figures.
- Zeros at the right or end of the of the number are significant if it is present at the right side of decimal points.
Example: 8.00 has three significant figures and 0.070 has two significant figures.
