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 then we were to find the density of an unknown liquid and find out what the substance was by matching its density with densities of substances listed in our packet. Describe how the concept of density relates to an object's mass and volume explain how objects of similar mass can have differing volume, and how objects of similar volume can have differing mass explain why changing an object's mass or volume does not affect its density (ie, understand density as an intensive property. To calculate the density of metals the experimenters had to find out the mass and volume of each and then use the following formula: d=m/v m or mass is the amount of. Density is mass per unit volume, so when measuring density, you find the mass of the object and divide it by its measured volume all measurements include some uncertainty, however, and certain kinds of errors can increase the uncertainty in your calculation. Density is an intensive property meaning that a substance's density will be the same regardless of the size of a sample for example, steel has a density of 785 g/cm 3 whether you have a tiny steel ball.
Sc8p84 : classify and compare substances on the basis of characteristic physical properties that can be demonstrated or measured for example, density, thermal or electrical conductivity, solubility, magnetic properties, melting and boiling points, and know that these properties are independent of the amount of the sample. Lesson plans on density for middle school teachers wet goes up must come down lab data sheet page 22 lesson 4 density is in the air by heavy metal objects. Lab four 2 specific heat of a metal there are five measurements that must be made to determine the specific heat of the unknown metal: 1 determine the mass of the piece of metal. 2 chemistry 101 lab 2 data sheet: 1 fill in the table below 2 show how the density was calculated for metals a and c 3 identify the metal by comparing the calculated density of the unknown to the density of known metals.
Lab: determining the density of unknown metals the materials list for this lab is simple: a balance, a graduated cylinder, and different pieces of metal you can use any metals that you might have available. The density you calculate for your sample with the density of the metal found in a reference book option 1: using the merck index or crc handbook of physics and chemistry, look up the density of the. The volume occupied by the metal can be determined using the mass of the cylinder (which is due to only the metal, not the void) and the density of the metal, which was determined previously in the lab (either al or brass, depending on the cylinder. Calculations & graph 1 calculate the mass, volume, and density of metal a and of metal b 2 graph the compiled class data on one set of axes.
Density determination of a metal cylinder density (d or ) is defined as mass (m) per unit volume (v), or mathematically: therefore two lab measurements are required: mass and volume. Density of a metal cylinder physics is a quantitative science, relying on accurate measurements of fundamental properties such as time, length, mass and temperature. Chemistry lab report 2 for later mass of metal sample initial volume of water final volume of water volume of metal density of metal identity of unknown. This classic lab is now available with extra large (easy-to-measure) 25 cm cubes of six different metals each set includes one cube each: aluminum, brass, copper, iron, lead, and zinc plus, students can use the density of the samples to calculate the purity.
Density of some common metals and alloys - aluminum, bronze, copper, iron and more sponsored links the density of some common metals and alloys are indicated in the table below. Metals density lab start by reading the problem by clicking on the title metals density problem in the top right corner place the following items on the workbench. Edit article how to measure the density of metals two methods: measuring density directly estimating density with archimedes' principle community q&a density is a basic property of matter defined as the mass of an object per unit volume.
Finally, i researched metals and alloys chart because it is very important to identify the unknown metal during this lab by used the quantitative and qualitative data according to baker, the density of a substance always differs from one substance to the other (p32 - 34. Lab 2: density of common metals the density of substance is a physical property that can be used to identify, in conjunction with other collaborating evidence, the identity and purity of a substance. Look at the class density of the unknown metal you graphed, which is the slope examine your own lab group's density for the same unknown record the standard density, given by the teacher, of the unknown that you graphed. General chemistry i (fc, 09 - 10) lab # 1: the densities of solids and liquids revised 8/19/2009 1 the density of a material may be defined as mass per unit volume.
Density 105 - phet interactive simulations. tony nguyen honors chemistry period 7 9/17/13 the density of metals lab backround: density is a constant relationship between the mass and volume of a specific type of matter measurements of both mass and volume can be obtained for a metal sample.
