    actual yield) Step 11: Show the calculation of the theoretical yield of calcium carbonate. The mole ration between CaCl2-.2H2O and CaCO3 is 1:1 that means that if we have 0.00680 moles of CaCl2-.2H2O we will get 0.00680 moles CaCO3 Convert the moles of CaCO3 to grams of CaCO3 = 0.00680 moles CaCO3 x 100 g CaCO3 1 mole CaCO3 = 0.68g CaCO3 Show the calculation of the percent yield. = Actual yield/Theoretical

    Experiment 1 mass determinations Objective: The purpose of this experiment is to see the difference of precision of different balances. When doing experiments we determine the mass my measuring the sample with a balance. There are many kinds of balances that measure to different precisions. This experiment shows the different results that two balances can give. Summary of Procedures Determine the mass with the triple beam scale to the most precise measurement possible for the scale.

    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

    Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

    Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different
