The question is based on a fallacy. Volumes can be reported in any number of significant figures.
In multiplication and division, the number of significant figures in the result is determined by the measurement with the fewest significant figures. For example, if you multiply 4.56 (three significant figures) by 1.4 (two significant figures), the result should be reported with two significant figures, yielding 6.4. Always round the final answer to reflect this limitation.
Two sf.
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.
42 has two significant figures.
687 to two significant figures is 690.
It varies. Volume may be reported with more or less significant figures. However, in general the result should not have more significant figures than the underlying data - otherwise, it would look more accurate than it really is.
Two significant figures the measurment 0.0255 g should be reported as 0.026g
When the value 4,449 is rounded to two significant figures the number should be reported as 4,400
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 number -2.006 should be reported with four significant figures. This is because all non-zero digits in the number are considered significant, and the zeros between the decimal point and the non-zero digit are also significant.
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
There are two significant figures which are the two 2s.
all the zeros are significant. there are four significant figures.
22.1 to two significant figures = 22
