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 687 to two significant figures?
687 to two significant figures is 690.
What is two significant figures of 23.43?
23.43 rounded to two significant figures is 23.
Why is the density expressed in two significant figures?
Expressing density in two significant figures helps to maintain the accuracy of the measurement while also keeping the data concise and easy to interpret. It strikes a balance between providing enough precision without overwhelming with excessive decimal places.

How many significant figures should the product of 0.12 g 1.8 g and 0.562 g have?
The product of 0.12 g, 1.8 g, and 0.562 g should have the same number of significant figures as the measurement with the fewest significant figures, which is 0.12 g in this case. Therefore, the product should be expressed with two significant figures.
