Suppose 2. 48g of ammonium acetate is dissolved in 0.300 L of a 73.0 mM aqueous solution of sodium chromate. Calculate the final molarity of acetate anion in the solution. You can assume the volume of the solution doesn't change when the ammonium acetate is dissolved in it.
Determine the molality and molarity of the HCL, if the solution has a density of 1.20 g/ml.
Calculate the mass (g) of CdC2O4 that will dissolve in 2000 mL of 0.357 M CdBr2 solution. The equation represents the solubility process.
what kind of product distribution and what does that tell you about the operating mechanism and the factors that affect product distribution?
