Chapter 1, Problem 1.65E

Here are two possible methods for measuring the volume of an irregular shaped object: a) Add it to a graduated cylinder containing a known volume of water. Measure the change in the volume of the water after the object has been added. The graduated cylinder is graduated in 1 mL increments. b) Add the object to a vessel that is full of water. Collect and measure the mass of the water that is displaced on a digital balance that provides mass to the 0.001 g. Determine the volume using the tabulated densities of water in table 1.1. Which method would be more likely to produce a more precise measure of the volume of an object?

A 1.50 cm3 sample of metal is found to weigh 7.08 g. Calculate the density of the metal in units of g/cm3 and g/mL what is =cm what is in =ml

A student experimentally determines the density of a metal cube. The edge length of the cube is measured using calipers. The cube's true density is 12.30 g/cm3. Use the student's collected data below and calculate the percent error for the measurement. Cube's Mass 45.961 g Edge Length 1.72 cm

A 147-g piece of metal has a density of 7.00 g/mL. A 50-mL graduated cylinder contains 20.0 mL of water. What is the final volume afterthe metal is added to the graduated cylinder?

A student completed Part C using a small sheet of aluminum metal (?=2.70 g/cm3). The sheet had a mass of 1.3648 g, a length of 2.05 cm, and a width of 2.20 cm. Calculate the thickness of the aluminum sheet in units of millimeters. Report only the numerical portion of your answer (and watch your significant figures!)

1.  A graduacted cylinder was filled with water until the voulume until the voulme read 55.0 mL. A rubber stopper was weighed and determined to have a mass of 6.782 g. The rubber stopper was carefully lowered into the graducated cylinder, and the volume was measure to be 60.6 mL. a) Calculate the denisty of the rubber stopper.   2. A 0.825 g pice of copper foil (d = 8.94 g/cm^3) measures 5.00 cm x 7.50 cm. a) Caculate the volume of the copper foil b) Caculate the thickness of the copper foil.

a particular stone with a mass of 56.78 g was put into a graduated cylinder containing 11.0mL. The water lebel rose to 19.0 mL .Determine the density of the stone in units of g/mL.

the diameter of a 16-gauge wire has a diameter of 0.05082 in. what length of wire in meter is found in a 1.60 lb spool of 16-gauge copper wire. desity of copper is 8.92g/cm^3

Iron has a density of 7.86 g/cm37.86 g/cm3 (1 cm3=1 mL1 cm3=1 mL). Calculate the volume (in dLdL) of a piece of iron having a mass of 4.32 kgkg . Note that the density is provided in different units of volume and mass than the desired units of volume (dLdL) and the given units of mass (kgkg). You will need to express the density in kg/dLkg/dL (1 cm3 = 1 mL1 cm3 = 1 mL) before calculating the volume for the piece of iron. Express your answer to three significant figures.
