Significant 0’s

Postby Samantha Burmester 3H » Mon Nov 19, 2018 11:03 pm

What are the rules for when a 0 is significant regarding the decimal point?
For example, how many significant figures are in the number 0.0850?

Zeroes between 2 nonzero numbers are significant
Ex) 202 has 3 sig figs
Final zeroes or trailing zeroes in the decimal portion are also significant.
Ex) 0.0850 only has 3 significant digits.

You can tell significant 0's by whether or not they contribute to the number's specificity. For example, 0.0850 is more specific than 0.085 because the latter is rounded, but 0.0085 is not a more specific version of 0.0850, it is just an entirely different number.

If you're still having trouble with significant figures, this has been a really helpful resource: https://lavelle.chem.ucla.edu/wp-conten ... OUT_SF.pdf

this is a different way to remember significant figures
it's helpful if you get confused between decimal present and no decimal
