goofyjumper 0 #1 January 16, 2013 Count the number of significant figures in these two different numbers 52000 52.000 I have as 52000 = 2 significant figures I have as 52.000 = 5 significant figures (note the decimal) Am I wrong here?----------------- I love and Miss you so much Honey!

chutem 0 #2 January 16, 2013 Don't know squat about chem.... 52.000 would seem to have 2 significant figures as 52 is the same as 52.000. I have no idea if this might apply to your situation. Someone who does will be along shortly. Quote Share this post Link to post Share on other sites
missbrz 0 #3 January 16, 2013 It depends on the precision of the 52000. it can have 2, 3, 4, or 5 significant figures. For instance if it is EXACTLY 52000 it is 5 sig figs. but if it is only precise to the 10's place it has 4 sig figs. you are correct on the 52.000 having 5 sig figs. make sense?

I've also seen it where if you don't have the decimal and you want to show that it is 5 sig figs then you draw a bar over it. Then again, I've never seen that done in practice. At any rate I would prefer to write it as 5.2000 x 10^4. A lot less ambiguous.well...I was going skydiving anyway. let's go. Earn your pancakes.

Never seen anyone use that in practice, even in research. If they really felt like even bothering with sig figs they did scientific notation.well...I was going skydiving anyway. let's go.
