Homework Help: Chem.

what is the six guidelines in determining significant figures?



Thanks:-)

With a decimal: from the decimal go to the right side of it until you see a definite number other than zero. Start there and how many numbers there are, including zero after that number are sig figs.

Example: 0.00987 SIgFig:3

Without a decimal: never count zeros unless it's sandwiched in between two other numbers.

Example: 304 = 3sigfigs
900870 = 5 sigfigs

With a decimal: to the left of the decimal, every number other than zero to start with and continue on to the other side of the decimal.

Example: 21.89670 = 7 sigfigs

James reposted the same question later and I gave him a hot link there to click on. Rather than going to the trouble of copying the link at this site, I simply referred him to his later post.
