Free Essays on William James

William James William James was born in New York City on January 11, 1842. His father was a rich man who spent his time entertaining the intellectuals of the time and discussing the religious mysticism of Swedenborg. This wonderful atmosphere for a bright young boy was thanks to his grandfather, an Irish immigrant with a knack for real estate investment! William was soon joined by a younger brother, Henry, who would grow up to be one of America’s premier novelists. All the James children were sent to European boarding schools and traveled through all the great capitals. At 19, after a stint as an art student, James enrolled at Harvard in chemistry, which he soon changed to medicine. He was not really interested in a career in medicine, but wanted to study the science that went with it. In 1865, he took advantage of a marvelous opportunity to travel the Amazon River basin with the great biologist Louis Agassiz, to collect samples of new species. While there, he began to suffer from a variety of health problems. In 1867, he went to study physiology in Germany, under Helmholtz and others. He befriended several notable early German psychologists, including Carl Stumpf. On the other hand, he had little respect for Herbert Spencer, Wilhelm Wundt, G. E. MÃ ¼ller, and others. In Germany, he began to suffer from serious depression, accompanied by thoughts of suicide. In addition, he had serious back pain, insomnia, and dyspepsia. In 1869, he came back to the US to finish up his MD degree, but continued to be plagued by depression. He had been reading a book by a French philosopher named Renouvier, which convinced him of the power of free will. He decided to apply this idea to his own problems, and seemed to improve. From 1871 through 1872, James was a part of "the Metaphysical Club," a group of Harvard grads who met in Boston to discuss the issues of the day. Included in the club were the philosopher Charles Peirce, Oliv... Free Essays on William James Free Essays on William James William James William James was born in New York City on January 11, 1842.

Molarity of Ions Example Problem

Molarity of Ions Example Problem This example problem demonstrates how to calculate the molarity of ions in an aqueous solution. Molarity is a concentration in terms of moles per liter of solution. Because an ionic compound dissociates into its components cations and anions in solution, the key to the problem is identifying how many moles of ions are produced during dissolution. Molar Concentration of Ions Problem A solution is prepared by dissolving 9.82 grams of copper chloride (CuCl2) in enough water to make 600 milliliters of solution. What is the molarity of the Cl  ions in the solution?Solution To find the molarity of the ions, we must first find the molarity of the solute and the ion to solute ratio.Step 1:  Find the molarity of the solute. From the periodic table: Atomic mass of Cu 63.55Atomic mass of Cl 35.45Atomic mass of CuCl2 1(63.55) 2(35.45)Atomic mass of CuCl2 63.55 70.9Atomic mass of CuCl2 134.45 g/molNumber of moles of CuCl2 9.82 g x 1 mol/134.45 gNumber of moles of CuCl2 0.07 molMsolute Number of moles of CuCl2/VolumeMsolute 0.07 mol/(600 mL x 1 L/1000 mL)Msolute 0.07 mol/0.600 LMsolute 0.12 mol/LStep 2:  Find the ion to solute ratio. CuCl2 dissociates by the reaction CuCl2 → Cu2 2Cl- Ion/solute Number of moles of Cl-/number of moles of CuCl2Ion/solute 2 moles of Cl-/1 mole CuCl2Step 3:  Find the  ion molarity. M of Cl- M of CuCl2 x ion/soluteM of Cl- 0.12 moles CuCl2/L x 2 moles of Cl-/1 mole CuCl2M of Cl- 0.24 moles of Cl-/LM of Cl- 0.24 MAnswer The molarity of the Cl  ions in the solution is 0.24 M. A Note About Solubility While this calculation is straightforward when an ionic compound completely dissolves in solution, its a tiny bit trickier when a substance is only partially soluble. Basically, you set up the problem the same way, but then multiply the answer time the fraction that dissolves.
