There would be five. The only time you do not count figures as significant is if they are zeroes behind a decimal, but before any other figure.
Ex/
0.000501 only has three significant figures, while 1.000501 has seven.

All of them are significant.
If you had a number such as 003.904, there would only be 4 significant figures because the zeros at the start do not mean anything, but ALL the rest of the numbers are significant.

∙ 13y agoJust count them left to right excluding leading zero's ==> five significant fig's

How many grams are in 5 mole of aluminum chloride?
First you take your compound AlCl3 and find the molar mass 26.98gAl+(3)35.45gCl= 133.33gAlCl3 Then you convert moles to grams 5molAlCl3x1g(over)1molx133.33g(over)1g=666.65gAlCl3 if you follow the rule of Significant Figures, 5mol has one significant figure (digit) so your answer needs to have 1 digit 700gAlCl3

What is significant figures of a number?
The significant figures are the ones which convey meaningful information about the measurement beyond the magnitude. Saying that a sample weighs .0000039 grams is better stated as 3.9 x 10^-6 grams or perhaps 3.9 micrograms. That's two significant figures. All the zeroes are not significant.
