Mole Essay Julissa Garcia Leon Andre Agassi College Preparatory Academy A mole is a scientific unit developed by chemist that measures large quantities of very small things‚ such as atoms‚ molecules‚ and other particles. There are three types of molar conversions; moles to particles or particles to moles‚ moles to mass or mass to moles‚ and moles to volume or volume to moles. The number of units in a mole is 6.02 × 1023. This number is called Avogadro’s number in honour of Amedeo Avogadro

something amazing and felt so inspired to want to go out and do something? Last October‚ my very close friend and co-worker Adrian completed his very first full marathon. I supported him through his training days‚ helped him fight his temptation to smoke‚ and cheered him on all the way to the day of his race; I waited for him at the finish line. As I was waiting for Adrian to cross the finish line in the pouring rain‚ I saw thousands of runners struggling to finish and others were ecstatic to see

Courtney Cox 5-4-10 THEA 1334 Final Paper Costume Design THE ROLE OF COSTUME DESIGN IN MUSICAL THEATER Imagine a classic Shakespearian play or Italian opera performed in hip-hugging jeans or baggy t-shirts; or imagine the period musical 1776‚ produced by the wonderful Stuart Ostrow‚ performed in the groovy attire of the 1970s. These performances would seem completely out of place and confusing. One would not be able to grasp the completeness of the story or have any understanding of the time

(12.01 x 2) + (1.0079 x 6)] = 290.704g/mol Mass of CuCl2= 0.850g Equation for reaction CuCl2 + 2DMSO -> CuCl22DMSO Mole ratio between CuCl2 and CuCl22DMSO = 1:1 Mole of CuCl2 = Mass/ Mr = 0.850/134.45 = 0.00632 moles Since the ratio between CuCl2 and CuCl22DMSO = 1:1‚ mole of CuCl2DMSO is also 0.0063 moles. To find theoretical yield of CuCl2.2DMSO Mass = Mr x mole =290.704 x 0.00632 = 1.837g The actual yield gained is 1.573g The percentage yield = (actual yield/ thereotical yield)

take the attitude that it is necessary to retain it to deter crime and “give criminals what they deserve.” My paper will analyze the arguments between Carol S. Steiker and Cass R. Sunsteins and Adrian Vermeule in terms of morality and argue for my own opinion on the issue. (Yes) Cass R. Sunstein and Adrian Vermeule -- Is Capital Punishment Morally Required? Cass and Adrian’s argument is based on the evidence that the death penalty‚ which requires a life-life tradeoff‚ has a powerful and deterrent

up by doing somethings that leads to them doing something else. For example‚ at the beginning of the episode a little boy is lost and then found with a finger. This sets up one of my favorite scenes where Adrian and the little boy are walking in the park to find where he found the finger and Adrian gives him disinfecting wipes after he touches something dirty.

values used to calculate the moles of magnesium and oxygen for each trial. The moles of magnesium and oxygen were then averaged (to reduce random error) and these values used to determine the experimental mole ratio for Mg : O. Uncertainties for each value were also calculated. Formula and worked examples for these are shown in table 2 below. Excel was used to graph moles of Mg verses moles of O. The equation for the line of best fit was then used to determine the mole ratio of Mg:O and thus the

Abstract: Liquid-vapor phase of acetone/chloroform was studied through distilling a series of mixtures with different mole fraction. When the mixtures were boiling‚ their vapor was condensed through a water column and collected in a receiving container. Refractive index was collected for starting mixture‚ distillate and residue for each sample. A boiling temperature versus acetone’s mole fraction was constructed to show the liquid-vapor phase diagram. The boiling temperature of azeotrope was determined

(II) Sulfate Purpose: The purpose of this lab is to find out how many moles of water there are in one mole of Copper Sulfate (CuSO x HO) and the percent by mass of water in the hydrate. This will be accomplished by heating a determined mass of the hydrate to remove the water‚ and by measuring the salt left over. Introduction: This laboratory experiment will be done to find out how many moles of HO are present per one mole in the hydrate CuSO. A hydrate is a compound that has a fixed number of
