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.

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.

How would you record a measurement of 16490 grams using only 2 significant figures?

The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.
