Density experiment in this experiment, you will determine the densities of liquids and solids now calculate the density of the metal from volume from 2 different methods ii) density of an unknown metal cube made of the same material as the metal cylinder: calculate its mass 2 a metal sphere weighing 1848 g is added to 2000 ml of. Laboratory experiments experiment no 2 the density of a material is defined as its mass per unit volume the symbol of density is ρ (the greek letter rho) 2 density and specific weight estimation for the regular shaped solid objects. Density is a measure of a substance’s mass-to-volume ratio for liquids and solids, density is usually expressed in units of g/ml or g/cm 3 these are equivalent since 1 ml is exactly equal to 1. Experiment: density objectives: • to determine the density of a known liquid (water) density is defined as mass per unit volume and can be calculated using the equation using a 100 ml graduated cylinder, obtain roughly 20 to 30 ml volume of an irregular solid sample 2 record your sample number (or substance name) 3 determine and.

2 density measurement in this equation, vcylinder1 is the ﬂrst approximation to the volume of the cylinder, r is the radius of the cylinder, d is the diameter of the cylinder, which is twice the radius of the cylinder, and h is the height of the cylinder. Extensive properties such as mass and volume depend on the amount of substance present and are not useful in the identification of a substance in this experiment, we will use three properties to identify a liquid substance - solubility, density and boiling. Measurement instruments ( mass, volume and density) exp # 1 phy 101h lab experiment 2 this preview has intentionally blurred sections sign up to view the full version.
Density is the relationship between the mass of an object and the volume which it occupies solid substances generally have the greatest density, normally in the range of 1 - 25 g/cm3 most liquids have densities between 05 - 5 g/ml, while the density of most gases under normal conditions of pressure and temperature is less than 5 g/l. Make a table containing the columns sample, mass, volume, and density, be sure to label the table, starting with table 2a2 make entries in the table for the samples liquid a1, liquid a2, liquid b1, and liquid b2. Mass, volume and density of a solid density is the ratio of the mass of a substance to the volume occupied by the object: density = mass/volume mass is found using a balance to find volume there are 3 methods, the first two are displacement experiment #2 density of an irregular shaped object. 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. Density is mass per unit volume take-home experiment sugar and salt 10 there is relatively little empty space between atoms in solids and liquids, so that the average density of an atom is about the same as matter on a macroscopic scale—approximately 10 3 kg/m 3.
In this experiment all volumes will be expressed in ml density, like color, odor, solubility, melting point, and boiling point is a physical property of density may be used in identifying a substance the density of a substance is defined as mass per unit of volume the density of a solid or the density of a liquid are both expressed as.

Density is calculated by dividing the mass by the volume plug in our measured mass at 100 grams and divide that by our measured volume of 100 ml water's density is 1 g/ml.
3 3 experiment 1 analysis of volume and density of a solid material and archimedes principle purpose : 1) the goal of this laboratory is to measure the mass and the dimensions of solids and to. Phy pack 8 –density of solids 2 produced by the physics group, university of cape coast as part of a delphe funded project title: determination of the density of solids. Lead cube has mass of 113 grams aluminum cube has mass of 27 grams since the samples have the same volume, they can be directly compared in order to see which one contains more matter in the sample size (more mass per unit of volume. Mass, volume and density purpose 1 familiarize with basic measurement tools such as the vernier caliper, micrometer, and weighing the density ρ of a substance is defined as the mass m per volume v, microsoft word - experiment_1 author.
Transcript of density of liquids and solids density of liquids and solids july 2013 volume = mass of water / density of water = 293862 g / ( 09982 g/ cm^3) = 294392 cm^3 f) mass of liquid 234381 g using this experiment we are able to calculate and obtain the densities for the unknown liquid and unknown metal. In this experiment you will determine the density of a liquid and a solid by procedures involving the determination of the mass of a sample together with its volume along the way, you will. The amount of matter contained in an object is called its mass and the amount of space occupied by the object is called its volume so, the mass of a unit volume of a substance is called its density. Experiment 2: measurement: length, mass, volume, density, & time read the entire experiment and organize time, materials, and work space before beginning remember to review the safety sections and wear goggles when appropriate.
35 | p a g e experiment #4 density figure i is a graph of mass, in grams, versus volume, in cc, for mercury we can calculate the slope of this line by using any two points lying on the line.
