It need not be.
Mathematically, the number of significant numbers should depend only on the number of significant digits in the measures for mass and volume used to calculate the density.
In real life, though, few substances are identical from one sample to another: their density can vary and a 2 sig fig density is usually the best compromise between accuracy and inclusion of all varieties of the substance.

How many significant figures does 6.022 have?
The number 6.300 has four significant digits. We must assume that the only reason for including the two zeroes at the end is to express the precision of the measurement (whatever it was that was measured to yield this number). If you were only confident about the first two numbers, you would express it as 6.3 rather than 6.300 as you did.
How many significant figures are in the number 0.030?
2 significant figures.
