Experiment 3 introduction to density introduction the purpose of this experiment is to understand the meaning and significance of the density of a substance density is a basic physical property of a homogeneous substance it is an intensive property, which means it depends only on the substance's composition and does not vary with size or amount.

Chem lab: density of a penny purpose: determine the densities of pennies which date from 1983 and later and of pennies from 1981 and earlier materials list: graduated cylinder water balance pennies background: density is mass per unit volume (d = m / v) the density of an object can be determined from the mass and volume of that object. Density of pennies lab before 1982, pennies were made of a copper alloy since then, they have been made with an outside coating of copper and an inner core of a different metal.

Sample traditional lab report - density of pennies hypothesis (based on the instructions provided) the density of pennies made before 1982 will be greater than the density of pennies made after 1982 data table 1 trial mass of 10 pennies made before 1982.
Measuring density objective the objective of the experiment is to calculate the densities of pennies and determine the unknown compositions of pennies minted in 1943, and compare the accuracy and precision of the results to the known densities of pennies minted between 1962 and 1982 and those minted after 1982.
Sample traditional lab report - density of pennies hypothesis (based on the instructions provided) the density of pennies made before 1982 will be greater than the density of pennies made after 1982 data table 1 trial mass of 10 pennies made before 1982 mass of 10 pennies made. A lab where the students study the density of pennies they will discover the limitations of measurements and the value of multiple trials in this lab, students will learn how to measure the volume and mass of an object and use that to compute density.
