Use the graph to answer both parts of this question about these three minerals. Do not use calculations. Mercury (Hg) or Copper (Cu) or Titanium (Ti)
A.
Which mineral is the most dense?

B.
Which mineral is the least dense?

C.
How can you tell just by looking at this graph? (Without making any calculations)

Mercury is the most dense whereas Titanium is the least dense.

Explanation:

Since Density = Mass / Volume, the slope of the line can immediately tell us its relative density between the metals.

Explanation:

The formula for density is:

As mass and volume increase, so does the density.

In this problem, the density is the line. So, the steeper the slope of the line, the greater the density.

So, mercury is the most dense and titanium is the least dense.
