Blog of the Day: Percent Composition

What is Percent Composition?
This is the percent by mass of each component found in a sample such as a coin.

The percent composition can be found by dividing the mass of each metal by the mass of the penny, and then multiplying by one hundred percent.

       2,4375 g zinc
       ________      X 100 = 97.50% zinc
       2.500 g total


      0.0625 g copper
      __________   X 100 = 2.50% copper
       2.500 g total


Percent Composition helps geologists to describe how much metal or mineral is present in a particular ore and to evaluate whether the ore should be mined.
