a. A student dissolved 20.00 g of Na2SO4 in enough water to make 250 mL of stock solution. How many mL of the stock solution would the student need to use in order to make a 150 mL of 0.100 M solution? b. In an acid-base titration, 82.56 mL of 0.175 M NaOH titrant reacts with 100.0 mL of an unknown concentration of HCl solution. What is the density of the HCl solution?

In the extraction of salicylic acid from water using dichloroethane, a student begins with 3 grams of the salicylic acid dissolved in 100 ml of water. After extraction with 20 ml of dichloroethane, drying and evaporation of the organic layer yielded 1.74 grams of salicylic acid. Assuming the student was efficient and did not lose any material, what is the distribution coefficient (Kd) for the system ? let Kd = (concentration in organic solvent) / (concentration in aqueous solvent)

In the extraction of salicylic acid from water using dichloroethane, a student begins with 2.9 grams of the salicylic acid dissolved in 100 ml of water. After extraction with 20 ml of dichloroethane, drying and evaporation of the organic layer yielded 1.972 grams of salicylic acid. Assuming the student was efficient and did not lose any material, what is the distribution coefficient (Kd) for the system ? let Kd = (concentration in organic solvent) / (concentration in aqueous solvent) a....

1.A student delivered 11.85 mL (V1) of 2.49 % stock solution (M1) using a graduated pipette into a 50.00 mL (V2) volumetric flask. Distilled water was added to the flask to the graduation mark and mixed well. Using the dilution equation (provided below), calculate the concentration of the diluted solution. (M1)(V1) = (M2)(V2) Report your answer to 3 decimal places. 2.Density is given by the equation density=mass/vol (d=m/V). Given that the density of magnesium is known to be 1.74 g/mL,...
