Two. When multiplying or dividing the answer is rounded to the fewest significant figures in the given measurements. 0.55 has only two significant figures, so the answer can have only two significant figures.
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.

Three significant figures: two before the decimal point and one after.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

The number 0.0950 has 3 significant figures. Those are the 9, 5, and final 0. The first two zeros on the left, are not significant.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
Two - the trailing zeros are just placeholders.
When rounding 5.05 to two significant figures, we first identify the two most significant digits, which are the 5 and the 0. The digit following the last significant digit is 5, which is equal to or greater than 5, so we round the last significant digit up by 1. Therefore, 5.05 rounded to two significant figures is 5.1.
