Practical Report Experiment 1 Abstract In this experiment we found that you can calculate the density of elements with close presotion with crude experiments Introduction The aim of this experiment was to see how close you could measure the density of atoms with crude experiments. The second part of the experiment dealt with Solubility of large ions and their Hydration enthalpy. Hydration enthalpy is the enthalpy change when 1 mole of an ionic substance dissolves in a solution to give a solution

Experiment #2 “Density Determinations” Report The objective for experiment #2 was “to determine densities of objects/salt solutions with different concentrations of salt‚ to see how density changes as a function of concentration.” In experiment #2‚ part II‚ calculations of Density of NaCL solutions were made from 0%-25% NaCL concentration. My hypothesis was that as the % increased‚ so would the density‚ because adding weight would increase the density of each solution. The density calculations in

The ratio of the mass per unit volume is density‚ d and is written as (D = m/v). Using the metric system‚ the ratio for solids and liquids is expressed in g/mL or g/cm. Matter expands and contracts according to

Mud weight otherwise known as drilling fluid density is a very important property of the drilling fluid which must be determined regularly during the drilling process. It is defined as the weight per unit volume of the drilling fluid or drilling mud usually expressed in units of g/cm3 or more conveniently lb/gal. Drilling fluid density or mud weight must be measured at regular intervals of the drilling process because as different formations are encountered during the drilling process‚ different

Shingala Dr. Campagnolo Chemistry H September 24‚ 2013 Lab on Density of Four Metals Conclusion In this lab we studied the densities of four different metals using a caliper‚ a digital scale‚ and a calculator. Three metals were pure elements like copper‚ iron‚ and aluminum. The fourth metal was an alloy which was brass. The purposes of this lab were to demonstrate that different metal elements have different densities‚ and that alloys have densities somewhere between those elements that compose them

Provide quality control by making sure the physical properties are within design specifications. Density is defined as the ratio of an object’s mass to its volume‚ measured by dividing mass by volume (density = mass/volume). This was accomplished using two different experimental methods‚ displacement and floatation. The theory is that
