Chapter 1, Problem 1.89SP
An experiment is performed to determine if pennies are made Of pure copper. The mass of 10 pennies was measured on a balance and found to be 24.656 g. The volume was found by dropping the 10 pen- nies into a graduated cylinder initially containing 10.0 mL of water. The volume after the pennies were added was 12.90 ml,. Calculate the density of the pennies. If the density of pure copper at the same temperature is 8.96 g/ cm3, are the pennies made of pure copper?

An experiment is performed to determine if pennies are made of pure copper. The mass of 11 pennies was measured on a balance and found to be 26.748 g. The volume was found by dropping the 11 pennies into a graduated cylinder initially containing 10.00 mL of water. The volume after the pennies were added was 12.90 mL.
As mentioned, the diameter of the cylinder is 8.35 cm, and the thickness (height) of heated portion of the piston is estimated 1 mm. Consider the shape of heated portion of the piston is a right cylinder, calculate the volume of this heated portion. Given the density of Aluminum is 2.71 g/cm3, what is the massed of heated portion of the piston?
A rock is placed on a balance and its mass is determined to be 20.140 g. When thesame rock is placed in a graduated cylinder that originally contains 11.34 mL of water, the new volume of water is 18.82 mL. What should the density of the rock be reported as?

- Finding the density of an unknown liquid. Having obtained the volume of the flask, the student emptied the flask, dried it, and filled it with an unknown liquid whose density she wished to determine. The mass of the stoppered flask when completely filled with liquid was 57.418g. Find the density of the liquid. a. First we need to find the mass of the liquid by measuring the difference: Massofliquid=gg=g b. Since the volume of the liquid equals that of the flask, we know both the mass and volume of the liquid and can easily find its density using the equation in lb. Make the calculation.
