Note: Express % strength with 4 decimal places. For ratio strength, state the volume only% Astelin nasal spray contains 0.1% azelastine hydrochloride and 125 mcg/mL of benzalkonium chloride as a preservative. A container is capable of delivering 200 metered sprays of 0.137 mL each. The percent concentration of benzalkonium chloride in the preparation is _______%, which is equivalent to a ratio strength of 1 in _____ w/v.
Given a reaction mixture of 40 mols of ethylebe glycol, 40 mols terephthalic acid, and 1.2 mol benzoic acid, what value of Xn would be expected if complete conversion (p = 1) of limiting factor were completed?
Q1. Dissolved 0.273 grams of pure sodium oxalate (Na,C,O.) in distilled water and added sulfuric acid and titration the solution at 70 ° C by using 42.68 ml of KMNO, solution and has exceeded end point limits by using 1.46 ml of standard oxalic acid (H; C;O.) with 0.1024 N. Calculate the normlity of KMN0.. Note that the molecular weight of sodium oxalate (Na,C,O.) = 134 and its equivalent weight = 67
Hexanoic acid was added to an immiscible biphasic solvent sysem, water and CCl4 at 20.0OC and the equilibrium concentrations of hexanoic acid were determined to be 3.66 g/L in H2O and 67.0 g/L in CCl4. Caluclate the distrubution coeffiecent (D1) of hexanoic acid in CCl4 with respect to water.
Suppose you have a soil that is made up of 10% organic matter with CEC = 200 cmol/kg, 40% kaolinitewith CEC = 10 cmol/kg, and 50% vermiculite with CEC = 100 cmol/kg.1- Calculate the overall CEC of the soil by taking a weighted average of the three soil components.2- What percentage of the overall CEC is contributed by the organic matter? How does that numbercompare to the 10% of the soil itself that is organic?
Explain why it is problematic to include a constraint such as the following in an LP model for a blending problem: Total octane in gasoline 1 blend $ divided by Barrels of gasoline 1 blended daily which is greater thanor equal to 10
An acid solution containing 2 per cent by mass of NaNO3, and an unknown concentration of HNO3 is used to regenerate a strong acid resin. After sufficient acid had been passed over the resin for equilibrium to attained, analysis showed that 10 per cent of resin sites were occupied by sodium ions. What was the concentration of HNO3 in the solution, if its density were 1,030 kg/cu.m.?
Compare and contrast an anticipatory standard to a reactionary standard by listing and describing some advantages and disadvantages.
How would the following errors change the calculated value of the percent oxalic acid in the radiator cleaner, that is would the calculated value of the percentage be high, low, or unchanged? Give a brief explanation of your reasoning. a. The experimenter consistently overshot the endpoint (i.e. added too much NaOH solution), of the titrations used to standardize the sodium hydroxide solution. b. The KHP used to standardize the NaOH was not pure, but contained approximately 10% by mass of the inert ionic compound potassium chloride, KCl. 3) Oxalic acid exists in the solid state as the monohydrate, H2C2O4•H2O. What would you use to calculate the percent oxalic acid monohydrate in the cleaner?
4) How would your calculated value of Kup be affected by errors introduced from the following sources? Be specific in your answer. State whether Ksp would be too large, too small, or not affected, and explain why that error would have that effect on Ksp c. Although the KIOs used to standardize the Na2S20s is labeled as 0.0100 M, its actual concentration is somewhat higher than 0.0100 M. d. Extraneous water is introduced from wet filter paper or wet funnels, or by washing the precipitate during the final filtration of Ca(IOs)2.
