1. Describe two different ways by which you could measure the volume of a small cube.

2. Which is more dense, lead or brass?

3. If the value occupied by a liquid 48mL and the density if 1.2g/mL, what is the mass of the liquid?

4. A recycling plant has chips of hight density poly(ethylene) (HDPE, d=0.92g.mL) used for plastic bottles and poly(vinylchloride) (PVC, d=1.406g/mL) used for plumbing and house siding. The chips of these two plastics were inadvertently mixed and it is your job to separate them. How would you do this?

1. You could measure the height, depth, and width of the cube, and multiply. Or, you could immerse the cube into water in a volumetric glassware. Because we know that water displaces 1 cubic centimeter for every 1 ...

Solution Summary

Two different ways to measure the volume of a small cube. Density and volume calculations.

...Calculate a) the thickness of the sheet b) the mass of one sheet. c) The volume of the pile d) The density of the paper e) The mass of a one square metre sheet ...

... Mass/Density = 910V/1000 = 0.91V m3. As the cube displaces volume of water equal to the volume of the immersed portion of the cube, from the above calculation...
