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.
To determine which measurements represent the same level of precision, you need to compare the number of significant figures or decimal places in each measurement. Measurements with the same number of decimal places or significant figures indicate a similar level of precision. For example, 0.0050 and 0.050 both have two significant figures, thus representing the same level of precision.
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.
2 of them.
Three significant figures: two before the decimal point and one after.

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.
Two - the trailing zeros are just placeholders.
To express 62.83 to two significant figures, you round it to 63. This is because the first two significant figures are "6" and "2," and the following digit "8" prompts rounding up. Therefore, the final answer is 63.
