An experiment requires a solution which is 98 mM glucose and 7 mM MgSO4. You have distilled water, a 3.4 M stock solution of glucose, and a 0.43 M MgSO4 stock solution in a lab. The experiment requires 10 ml of the solution in a test tube.
(a) What volume of the stock glucose solution do you need in the test tube?
(b) What volume of stock MgSO4 solution do you need in the test tube?
(a) What volume of the stock glucose solution do you need in the test tube?
(b) What volume of stock MgSO4 solution do you need in the test tube?
a. Calculate K_sp of Ag_2 CrO_4. Organize your answer so that your solution is logical. Make sure that your K_sp has correct significant figures.From the experiment CU = 0.00016 mol. Also 〖Ag〗_2 〖CrO〗_4 = 0.0016 mol
b) Calculate percentage error. Ag2CrO4 arrows 2Ag+ + CrO42-
b) Calculate percentage error. Ag2CrO4 arrows 2Ag+ + CrO42-
how many moles are in 28 grams of Na2SO3
The equilibrium constant for the formation of Cu (CN) 42- is 2.0 x 1030. Calculate the value of pCu2 +, ie -log [Cu2 +], if 2.24 g of CuCl2 are dissolved in 1000 L of a 0.910 M solution. NaCN. The addition of CuCl2 does not affect the volume (the final volume is always 1,000 L).
The solubility product of Cu (OH)2 is 4.8 x 10-20. Calculate the value of pCu2 +, ie -log [Cu2 +], in an aqueous solution of NaOH which has a pH of 12.68 and which is saturated with Cu (OH) 2.
The solubility product, Ks, of Cd3 (PO4) 2 and 2.5 x 10-33. What is the solubility (in g / L) of Cd3 (PO4) 2 in pure water?
Determine the pH change when 0.091 mol HCl is added to 1.00 L of a buffer solution that is 0.488 M in CH3COOH and 0.310 M in CH3COO-.
pH after addition − pH before addition = pH change =
pH after addition − pH before addition = pH change =

I have used other site but this one is by far the best one to use. Other sites that I used were in a different country and oftentimes they didn’t meet due dates which is really important plus, the quality of work was often poor… Assignment Experts reply quickly, and the quality of work is bar none… I always get what I ask for… Grate job!!!!! Highly recommend this site to anyone needing that extra help..
