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.

Which is 459.567L expressed to three significant digits?
460. (the period/decimal point is necessary; otherwise 460 would be considered two significant figures)
How many significant figures in 42?
42 has two significant figures.
What is the mass of 136 mL of Mercury?
If you know the density of mercury, you can determine the mass of a specific volume of mercury. Mercury has a density of 13.534g/cm3. 1cm3 = 1mL, so we can restate its density as 13.534g/mL. Density = mass/volume. If we know any two variables, we can manipulate the density equation to find the third variable. In this case, we know volume and density, so to find the mass, do the following calculation: Mass = density x volume Mass Hg = 13.534g/mL x 136mL = 1.84g Hg* *The answer is limited to 3 significant figures, because 136mL has only 3 significant figures, even though the density has 5 significant figures. When multiplying or dividing, the answer is limited to the same number of significant figures as the measurement with the fewest significant figures used in the calculation.
What is 10096 to two significant figures?
Rounded to two significant figures it becomes 1.0e4
What is 3.579 to two significant figures?
Rounded to two significant figures it becomes 3.6
Why is the density expressed in two significant figures?
It is not always expressed in 2 sig figs. The number of sig figs depends on the accuracy of your measurements of mass and volume to calculate the density as well as any variables that you are expected to use the density with. There is no point in having a density expressed to 15 significant figures if then you are going to multiply it by volume expressed to 1 sig fig to determine the mass.
What is 62.125 kg rounded to two significant figures?
It is: 62 kg
How many significant figures are in 149.0?
Four. When the decimal point is expressed, trailing zeros are significant.
