Calculate the molar concentration of a potassium chloride solution if 2.4 liters contains 2.00 moles of KCl. Calculate the molar concentration of 15 frams of KCl in 1.5 liters of solution.
Converting Voltages, Convert the following voltages. Assume the silver-silver chloride and calomel reference electrodes are saturated with KCl, giving cell potentials of +0.197 V and +0.241, respectively.
write four balanced equations for the reactions to separate and recover m-nitroanilin benzoic acid and naphthalene.
Suppose that 0.3 g of AlOOH (FM 59.99) plus 150 mL of 3M KOH are diluted to 1L to give the same species produced by Al(OH)3. Write mass balance equations for aluminum and potassium.
