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.

I have a 40 lb container that measures 14x20x30 and need to find the density. I also have another 40 lb container that has a volume of 1.9 gal. How do you find the density for both to see which one is lighter?

After a label fell off a bottle containing a clear liquid which is believed to be benzene, a chemist measured the density of the liquid to verify its identity. A 25.0 ml portion of the liquid had a mass of 21.95g. A chemistry handbook lists the density of benzene at 15 degrees celcius 0.8787g/ml. Is the calculated density in agr

A certain object weighs 100 N. When placed in water it weighs 72 N and when placed in oil it weighs 82 N.
a) What is the density of the object?
b) What is the density of the oil?

Questions:
1. If the sun which is 93,000,000 miles away away from Earth was to go out, how long would it take for us to know that this had happened? Light travels at a speed of 3 x 10^8 meters/second.
2. What would the density be (in g/cm^3) of a block that is 4 cm by 15 cm by 12 cm, and has a mass of 4.3 kg?
3. An ob

A magnetic field has a magnitude of 12 T. What is the magnitude of an electric field that stores the same energy per unit volume as this magnetic field?

Imagine that you have a solid cube composed of Material X. You put the cube into a beaker filled with water. The cube sinks to the bottom of the beaker and sits there, at rest, on the bottom.
Which of the following statements are true? (Give ALL correct answers: B, AC, BCD, ... , or None)
A) The buoyant force on the cub
