Sig Figs

[Claire_Kim_2F]

How many sig figs would 0.003204 have? I assumed it would have four because the zeros before do not count but I just wanted to double check.

I also got 4 sig figs which counts the 3204.

there are four sigfigs. the leading zeroes don't count as significant figures.

I also got 4 significant figures: 3204

Another way to write it would be 3.204 x 10^-3 which is also 4 sig figs if that helps you to visualize it.

Hope that helps! :)

Hi,

When trying to solve for significant figures, it is best to put it in scientific notation like someone mentioned above. So 3.204 x 10^(-3) shows there are 4 significant figures. Dr. Lavelle posted a significant figures review on his website if you need to brush up on those concepts.

Here are the sources Dr. Lavelle provided on his website about sig figs.

There are 4 significant figures since leading zeros do not count. The zeros in middle of 3024 in 0.003024 count because it is in between significant digits.

If significant numbers are an issue for anyone, I studied the topic using mainly this image:

I think it really sums up everything simply and clearly :)

Here are some basic sig fig rules for you to refer to, if you want them quick and easy:

1) ALL zeros between non-zero digits are significant (1.077 has 4 sig figs)

2) Leading zeros are NEVER significant; they are just place-holders and this is easier to see if you put your number into scientific notation (0.0056 has 2 sig figs)

3)Trailing zeros are only significant if there is a decimal in the number (9800.0 has 5 sig figs while 9800 has only 2 sig figs)

Yes there are 4 sig figs.
