technique is: Number Moles Concentrated Solution = Number Moles Dilute Solution. An instrument called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded from the meter. In the lab‚ multiple homogeneous solutions are made. There was not a way to determine the differences in concentrations‚ but the Spec 20 made it possible to measure the difference. The Beer-Lambert Law is a graph used to record

If I were to visualize this avenue of reality and unknown reality‚ Reality is already a familiar path we walk on yet there are roads that

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

Diffusion and osmosis go hand-in-hand. Osmosis is generally the same as diffusion‚ however‚ deals solely with water. Osmotic pressure is the pressure of a solution against a semi-permeable membrane to prevent water from flowing into the membrane. In this lab‚ we are going to study tonicity; tonicity is the measure of this osmotic pressure and is the differential of pressure between two solutions separated by a selective membrane. To help identify the relative concentrations of solute particles of different

Joshua Berkebile 8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object
