why the last zero is not significant
anonymous
  • anonymous
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)

the last zero does count

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

would still be 4 sig figures

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

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.

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