How could you identify a pure metal if you have a balance, a graduated cylinder, and a table of densities for metals?

Wierd boy has the right of it...using the graduated cylinder with water in it will give the displacement in milliliters and 10 milliliters equals one centiliter which just happens to be equal to one cubic centimeter...find the displacement, convert to cubic centimeters and divide it into the mass figure obtained from the balance and get X grams/cubic centimeters to find the density, then find it on the chart...if it doesn't match up exactly, you know that it isn't pure, it's an alloy.
H2O, water, has a density of 1.00 grams/cubic centimeter.

Pure metals have the highest density

the balance will give you the mass
the increase in the level of liquid in teh cylinder gives the volume in liters
mass divided by volume = density
Then use your chart
