Easy 3 Rules

Postby 805421690 » Sun Oct 11, 2020 11:44 pm

Hey guys, I think the hardest part for me with sig fig was trying to remember the rules. So I wanted to share the easiest way to explain how to find significant figures:
1. Any # greater than 0 is significant
2. Any number between a significant # is also significant. Meaning if it qualified for step one then any number that did not can be counted if it is between significant numbers.
3.Anything after a decimal is counted as a significant number, any trailing zeros as well

Thank you for this! I don't know why, but sig figs have always been the most challenging thing to wrap my head around, though its one of the simplest topics.

Thank you so much! My biggest problem has been just figuring out the trailing zeros, but these rules helped, so thank you. :)

Hi! I've had trouble figuring out significant figure rules throughout my time in chemistry.

Rule #3 (Anything after a decimal is counted as a significant number, any trailing zeros as well)

For the number 0.00450, are there 3 or 5 significant figures? It's numbers like these that I'm always confused on.

In the number 0.00450, there are 3 significant figures, which are the last three digits in the number from the right side; the trailing zero is counted, as well as the other two non-zero digits.
