Procedure as you perform the experiment, record your data in data tables 1 and 2 1 determine the mass of two different unknown metal samples to the nearest 001 gram, using a centigram balance. Density is a property of a material that is unique to that object it can be used to calculate the mass of things that cannot be measured like bridges, and crowns.

2) determine the density of each of the above, using a hydrometer and an ungraduated cylinder read the density from where the liquid crosses the hydrometer's scale 3) weigh and record the mass of an unknown metal cylinder. The objectives of this laboratory are: a) to use standard laboratory measurement devices to measure length, volume and mass amounts b) to use these measurements to determine the areas of shapes and volumes c) to determine the density of water d) to determine the density of a solid and use this to. The calculation of density by division of mass and volume max m & emily o 09/08/13 introduction/ purpose/ objectives the purpose of this lab was to experimentally determine the density of three unknown objects, and to identify the objects based on their densities. In this experiment, you will measure masses and volumes to determine density four different metal cylinders are investigated in parts 1-3, three different methods are used to find volume of two solid metal cylinders (al and brass.

Density is a measure of how much mass is contained in a given unit volume (density = mass divided by volume) if mass is a measure of how much stuff there is in an object or liquid, density is a measure of how tightly that stuff is packed together. Mass & volume lab 2 part b: finding mass by difference 1 find the massof an empty 250ml beaker record in data table 2 2 using the graduated cylinder, obtain 150 ml of water. Experiment measurement: length, mass, volume, density, and time density can be determined by the water displacement method or by using archimedes' principle in the water displacement method, an object is placed into a graduated cylinder with a known. Why do objects that are the same size sometimes have different weights the answer has to do with their density an object's density is determined by comparing its mass to its volume.

Page 2 of 5 in part b of this lab, the density of aluminum will be determined using aluminum pellets again, mass will be measured using an electronic balance, in grams (g. • density is defined by the ratio of the mass of a substance to its volume • for an object to float, relative to its surroundings, it must be less dense than its surroundings. An object's density is defined as the ratio of mass to volume density is used across geology, physics, and many other physical sciences the property also determines whether or not an object would float (known as buoyancy) in water, which has a unit density of 1 gram per cubic centimeter (g/cm 3. In terms of density, differentiate between an object which floats in water and an object which sinks in water 7 show how one would set up a ratio to determine the mass of a substance with a density of 84g/ml and a volume of 20 ml. The mass of atoms, their size, and how they are arranged determine the density of a substance density equals the mass of the substance divided by its volume d = m/v objects with the same volume but different mass have different densities.

Density not its mass a 40 g cork will float on water because it is less dense than water a 40 g cork will float on water because it is less dense than water suppose the cork had a mass of 1000 kg. Density is defined as being equal to an object's mass divided by its volume the task for our lab was to determine the density of water and compare our recordings to the actual density of water listed in our lab packet. If two objects have the same mass but different volumes than their density values would be different because, density depends on mass/volume if two objects had the same mass and volume, than their density would be the same. The mass of any object is determined by comparing its mass with the mass of known object or objects ( ie , it is weighed) the volume of a liquid is measured using a graduated cylinder, a pipet, or some other. Chem 100 experiment 2 revised 12/07 3 finding density using the measured masses and volumes calculate the densities of each object show the setup for.

Mass and volume, the quantities used to determine density are extensive properties because they are dependent on (and change) with the quantity of sample since density is a ratio of mass to volume, it remains constant for a substance. Students will be able to compare and calculate the densities of various materials using their masses and volumes content statements: - objects with the same mass but different volumes have different densities. Experiment 1: finding densities of irregular objects experiment 1: in class title: measuring the mass and volume of irregular objects and using it to calculate their densities.

- Experiment 2 - density name _____ lab section _____ density of a liquid - mass by difference the mass of a 250 ml sample of an unknown liquid is determined by difference.
- In order to determine the density of a material, you need to determine the mass and the volume of a sample of the material in the laboratory, it is far easier to determine the mass of an object precisely (using a balance) than it is to determine the volume of the object.

Determine the mass of the 200 ml by reading the electronic balance directly, or if using a triple- beam balance, record the total mass (cylinder + liquid) and then subtract the mass of the graduated cylinder. C find x, and use x to determine the mass fraction of brass in the mixed cylinder, 1 - x x has a range of possible values from zero to one (0 - 100%) if your mixed cylinder's density is. The formula to determine the density (d) of an object is equivalent to its mass (m) in grams, divided by the volume of the object (v), in milliliters, or d=m/v in order to determine density we must determine the mass and volume. Lab activity 1 measurements in science: mass, volume, and density purpose: the purpose of this experiment is find the density of two metals using their mass and volume introduction: the purpose of the experiment that was conducted was to measure and calculate the density of two different metals.
