Answer on Inorganic Chemistry Question for siobhan
a student was asked to find the relative atomic mass of element X. crystals of the chloride of X were know to have the formular XCl2 .6H2O.the student dissolved 2.03g of the crystals in water, and then added an excess of silver nitrate solution to the solution formed. a white percipitate of silver chloride was formed, which was filtered, dried and weighed. 2.87g were formed. Ag+Cl---AgCl calculate: the number of moles of silver chloride formed? the number of moles of X chloride in the solution? the mass of 1 mole of XCl2.6H2O? the relative atomic mass of X?
i am grouping my way at these maths , which I could not do with out you. You cover every question step by step and of top quality , inch by inch you guide me along the path, maybe a little expensive for me (71 years old who had a stroke) but top quality.
