1. mridul1

3

why the last zero is not significant

3. mridul1

in counting the no. of significant figures zeros at last are not considered significant because the do not increase the accuracy of the measurement instead they tend to increase the power of the number. the number can be written as 30.2 x (10^2)

4. sonofa_nh

there's 4

5. sonofa_nh

the last zero does count

6. sonofa_nh

the only time a zero doesn't get counted in sig figures is when it is before the whole number...such as 000000003020

7. sonofa_nh

would still be 4 sig figures

8. Stleaveland

No, there's 3 as there isn't a period afterwards the zero so it doesn't count.

9. stormfire1

The number is ambiguous in the significant figure realm. If it had a decimal at the end, the answer would clearly be 4. In the strictest sense, the answer is 3 since leading and trailing zeros are not significant if they only serve as placeholders.

10. pnm

we can not tell how many significant figures since the number given is uncertain.

11. thabs

this doesn't make any sence because there is a missing decimal point at the end of the given number.
