    Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies, record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water, record the volume in data table. Carefully place the pennies into the graduated cylinder, record the final volume of the water in data table. To find the volume of the pennies, subtract the final volume from the initial, record the data. Repeat this procedure twice more...

  • Percent Mass of Copper in a Penny

    Percent Mass of Copper in a Penny Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance, e is a constant called molar absorbency, l is the length in cm, and c is the concentration). Using Beer’s Law in this...

    Abolish the Penny Between 2001 and 2006, there has been an increase of .6 cents for the reproduction of the penny. This increase displays economic problems that may lead to fatal ones. The penny is composed of 2% copper and 98% zinc. These elements are exponentially in demand causing the price of these materials to skyrocket. Many Americans think the penny is putting our country in jeopardy with financial losses. This meaningless coin is losing money for the mint, and should be abolished. ...
