In titration labs, you used weak acid hydrogen phthalate (KHC8H4)4) as a primary standard in an acid/base titration "KHP", How much of this weak acid would have to be weighed out to prepare 100.0 mL of a 0.240 M KHP solution?

...

If you actually weighed out 8.50% more KHP than required what would be the actual molarity of the solution?

...

If you used the prepared KHP solution in a lab experiment which concentration would you need to use in your calculation? Explain your reasoning.

a solution that has been prepared with known molarity

What is the molarity of a potassium bromide solution that is prepared by adding 400 mL of water to 25 mL of aqueous 2.00 M potassium bromide solution? Assume volumes are additive, report answer to three sig. figs.

...

Part A - Preparation of 100.0 mL of an aqueous solution of sucrose, C12H22O11, with specified molarity

Assigned Molarity = 0.0441 M

Volume of Solution = 100.00 mL

Mass of Sucrose = ? Answer = 1.51 g

Explanation - 0.1 L x (0.0441 M / 1 L) x (342.308 g / 1 mol)

Calculation - Mass of sucrose required

Part B - Dilution of a 1.0 M NaCl solution to a specified final volume

Assigned Final Volume = 76.2 mL

Molarity of "Stock Solution" = 1.0 M NaCl

Volume of "Stock Solution" = 10.0 mL

Molarity of Final Solution = ?

Answer = 0.13 M

Explanation - (1.0 M NaCl x 0.01 L) / 0.07621 L = M2

M1V1/V2 = M2

Calculation - Find molarity of NaCl

Part C - Preparation of 100.00 mL solution with a specified mass of alum, KAI(SO4)2.12H2O. Student will determine the molarity of a particular ion (K+, Al+3, SO4-2) in the resulting solution (K+, Al+2, SO4-2)

Answer = 0.078 M Na Cl

Explanation - 1.84 g Alum (1 mole/474.39 g Alum) = 3.8787x10^-3 mole

3.8787x10^-3 x 2 = 7.7573 x 10^-3 mole

7.7573 x 10^-3 / 0.1 L = 0.078 M NaCL

Calculation - Molarity of ion in final solution

Part D - Preparation of a sucrose solution at a specified % (m/m0 sucrose and a specified total mass of solution

Assigned Mass of Solution = 35.3 g

Assigned % by Mass Mass of sucrose = ? Mass of Water = ?

Answers = 25.5 g Sucrose and 9.7 g H20

Explanation - Suroces = 35.2 g x 0.725 (m/m)

Water = 35.2 g - 25.5 g

Calculation - Masses of sucrose and water required (dry lab)

Part E - Preparation of a solution with specified molality of sucrose using a specified mass of water

Assigned Molality = 0.339 g

Assigned Mass of Water = 52.2 g

Mass of Sucrose = ?

Mass of Prepared Solution = ?

Answer = Explanation -

Calculation - Masses of sucrose required in solution (dry lab)

Part F - Prepare a standard solution of KIO3 for Experiment 18

Volume of Solution =

Mass of KIO3 = Molarity of KIO3 = Answer = Explanation -

Calculation - Molarity of prepared solution

(Important to use deionized water, since solution will be used as a standard)

Ace 7.2K answers 43.3M people helped Answer: 0.000125 moles Explanation:

Firstly, we need to know the meaning of the 0.5M. This simply means 0.5 moles are present in 1L or 1dm^3. 0.5M could also be written as 0.5moles/L.

Now, we know that there are 0.5 moles in 1L, we now need to calculate the number of moles in 0.5ml.

It is necessary to know that 1000ml = 1L.

Now if 0.5 moles = 1000ml

xmoles = 0.25ml

X = (0.25 * 0.5)/1000 = 0.000125 moles
