Calculate the Redlich-Kwong parameters of fluorine from the values of the critical constants

6 x 10⁻⁵¹ = (0.15 M)² [S²⁻] [S²⁻] = (6 x 10⁻⁵¹) / (0.15 M)² Calculating, we find the minimum concentration of sulfide ion required: [S²⁻] ≈ 2.7 x 10⁻⁴⁹ M. check it calcution is write

It required 66.66 mL of 2.000 M HBRO3 to titrate (neutralize) 50.00 mL of an Al(OH)3 solution. What is the molarity, M, of the aluminum hydroxide solution ? 3 HBRO3 + Al(OH)3 З Н-0 + Al(BrOз)з Answer a few questions before giving the final answer in the last problem. How many moles of Al(OH)3 are required to neutralize the acid ? A. 0.3999 mol B. 0.1333 mol C. 0.09998 mol D. 0.04444 mol

A solution is made by dissolving 0.641 mol of nonelectrolyte solute in 763 g of benzene. Calculate the freezing point, T;, and boiling point, Tp, of the solution. Constants can be found in the table of colligative constants. %3D °C Tp = °C

You wish to determine the %concentration of a stock solution of brilliant blue FCF (MW=792.8grams/mole; extinction coefficient,25=97000M1cm 1). You take 5ul of the stock and dilute up to 1ml. You take 10ul of this dilution an dilute it up to 500ul. Finally you take 1ul from this dilution and dilute it up to 1ml in a 1cm diameter cuvette. You obtain an As91=0.001 SHOW YOUR WORK. Do not forget units. 1. What is your total dilution factor? 2. What is the molar concentration of the dye in the original stock? 3. What is the % concentration of the dye in the original stock?

What is the Michaelis-Menten equation and what is it used for?
