The density of gold metal is 19.3 g/cm3, while that for silver is 10.5 g/cm3. Suppose you had the same size bar of each metal, with the dimensions 2.00 in x 10.0 cm x 760 mm. Volume of a cube is height x length x width.
Which bar would have the greatest mass?
Which bar contains the greater number of atoms?
If the two bars were melted and mixed together to form an alloy (or mixture) what would be the total mass?

- A materials engineer has filed for a patent for a new alloy to be used in golf club heads. The composition by mass ranges from 25 to 31% manganese, 6.3 to 7.8% aluminum, 0.65 to 0.85% carbon, and 5.5 to 9.0% chromium, with the remainder being iron. What are the maximum and minimum percentages of iron possible in this alloy? Use Figure 2.12 to snake a prediction about how the density of this alloy would compare with that of iron; justify your prediction.arrow_forwardif an average fluorine atom has a mass of 3.82 x 10-23 g, what is the mass of a magnesium atom in gramsarrow_forwardA.
