Unit 6 Reactions And Stoichiometry

Tutorial 4 SOLUTION STOICHIOMETRY - EIU

Chemical reactions are written in terms of moles of reactants and products; this molarity concentration unit relates moles of solute to volume of solution. Thus, easily measured solution volumes provide a simple method of measuring moles of reactants. EXAMPLE: What is the molarity of a solution made by dissolving 5.67 g of potassium chloride

10.1 Equation Stoichiometry 369 The ratio of moles of P 4O 10 to moles of P (which came from the subscripts in the chemical formula, P 4O 10) provided the key conversion factor that allowed us to convert from units of phosphorus to units of tetraphosphorus decoxide. Now let’s assume that you have been transferred to the division responsible for the
