How would you be able to go about calculating the density of 1 penny?
If you were asked to calculate the density of 1 penny, you might have difficulty because the small amount of water displaced by 1 penny would not be measurable.
The formula for density is--density equals mass divided by volume. If you think it would be difficult to measure the small amount of water displaced in your graduated cylinder, then, why not get the density of five pennies? Weigh five pennies to get their mass using a balance or digital scale and record the amount. Next, measure the original volume of water in a graduated cylinder and record that amount. Place the five pennies into the cylinder and record the new volume. Subtract the new volume minus the original volume, to get the volume of water displaced by the five pennies. Divide the mass of five pennies, by the volume of five pennies, to get density of five pennies. Divide your answer by five to get the density of one penny.
